1 SYNTAX LIN 1310

2 Syntax is the component of grammar that deals with sentence structure. Before we can talk about syntax, we need to discuss the nature of linguistic competence and the nature of grammar

3 The nature of grammar Linguistic competence: Theoretically permits infinite production of novel utterances, including sentences. How can our brains handle a system capable of infinite production? Answer: The elements of the system are not infinite. They are finite in number.

4 Grammar A system that permits infinite creativity with a relatively limited number of elements, including speech sounds and the rules for combining them into words and sentences. The rules for making sentences are called the syntax of the language. What are these rules like and how are they stored as part of competence?

5 The Rules of Syntax Does knowing the rules of syntax involve storing the syntactic structures of all possible sentences in our heads as a set of templates with slots to fill? No, it does not. Here are for reasons why not:

6 Reason 1 1. Rules of syntax allow sentences to be infinitely long. (The only limits are imposed by performance.)

7 Reason 2 2. All possible sentences have not yet been uttered.

8 Reason 3 3. Our storage capacity is finite.

9 Reason 4 4. Sentence interpretation is structure dependent. That is, it relies on more than a simple linear (one word after another) organization. (This will be explained further.)

10 The Nature of Syntax The following slides present a number of illustrations of the nature of syntax and facts about language that a linguistic theory of syntax must account for.

11 Facts syntactic theory must account for: Fact 1 1.How words in a sentence are assigned specific roles with respect to one another. For example, in English active sentences: The first noun is the subject or doer of the action or agent. The second noun is the object or receiver (or theme or patient) of the action.

12 Facts syntactic theory must account for: Fact 1 Thus different interpretations for: The dog chased the cat. subject verbobject The cat chased the dog. subject verbobject

13 Facts syntactic theory must account for: Fact 1 Word order varies across languages. In German, it’s subject, object, verb: Das Kind wird die Schwester lehren. The child will the sister teach. subject object verb

14 Facts syntactic theory must account for: Fact 1 For some languages, like Welsh, the preferred order is verb, subject, object. For example: darllenais i y llyfr read I the book verb subject object

15 Facts syntactic theory must account for: Fact 1 Other languages may rely more on some form of morphological marking than on word ordering to assign roles to words in sentences. However, these languages still have a most common or canonical word order. The other permissible word orders tend to slightly alter the focus of the sentence. See Japanese example on the next slide.

16 Facts syntactic theory must account for: Fact 1 Canonical word order in Japanese: ‘Yumiko scolded the child’: Yumiko-ga sono kodomo-o sikat-ta yumiko-NOM that child-ACC scold-past subjectobject verb Alternative order (focus on object): Sono kodomo-o Yumiko-ga sikat-ta that child-ACC yumiko-NOM scold-past object subject verb

17 Facts syntactic theory must account for: Fact 1 The most typical word order in a language is called its canonical word order. 95% of the world’s languages have one of the following canonical word orders: SVO – Canadians like hockey. (English) SOV – Canadians hockey like. (German) VSO – Like Canadians hockey. (Welsh) VOS OVS OSV – rare or nonexistent

18 Facts syntactic theory must account for: Fact 2 2.Sentences with different surface structures and word orders can have the same interpretation of who’s doing what to whom, even in a language with strict word order and no specific marking of subjects and objects. Examine the following sentence pairs from English:

19 Facts syntactic theory must account for: Fact 2 scrambled order: The boy gave the toy to the girl. direct indirect object object The boy gave the girl the toy. indirect direct object object

20 Facts syntactic theory must account for: Fact 2 active: The student solved the problem. (agent/subject) (theme/object) passive: The problem was solved by the student. (theme/object)(agent/subject)

21 Facts syntactic theory must account for: Fact 2 declarative: Everyone is happy. (verb) yes/no question: Is everyone happy? (verb)

22 Facts syntactic theory must account for: Fact 2 declarative: You have been there. auxiliary yes/no question: Have you been there? auxiliary

23 Facts syntactic theory must account for: Fact 3 3.Sentences contain discontinuous elements which are understood as part of the same structural constituent, as in: perfect (auxiliary ‘have’ + suffix ‘-en’): I have eaten. progressive (auxiliary ‘be’ + suffix ‘-ing’): I am eating.

24 Facts syntactic theory must account for: Fact 3 Wh question: What are they looking at? Object Declarative: They are looking at the dog. object NB: Although ‘what’ has moved to the front of the question sentence, it plays the same syntactic role as ‘the dog’ does in the declarative. Both are part of the predicate.

25 Facts syntactic theory must account for: Fact 4 4. It is possible for sentences to be embedded inside other sentences. The property of grammar which permits such embedding is called recursiveness.

26 Facts syntactic theory must account for: Fact 4 Recursiveness also allows sentence constituents (parts) to occur inside other constituents. See the string of adjectives for the subject noun ‘dog’ in the following example: The big gray shaggy friendly dog brought me the newspaper.’

27 Facts syntactic theory must account for: Fact 4 In the following examples, note how a sentence can grow as more strings of adjectives, prepositional phrases and embedded sentences are added: The dog was sleeping. subject The big dog was sleeping. subject ‘dog’ + one adjective

28 Facts syntactic theory must account for: Fact 4 The big ugly guard dog at the factory was sleeping. Subject ‘dog’ + string of adjectives + prepositional phrase

29 Facts syntactic theory must account for: Fact 4 The big ugly guard dog at the factory which produces pillows that some people are allergic to was sleeping on the road that leads to the quarry where they found the hobo who had been strangled with a shoelace that was later shown to have been stolen from the woman on Main Street whose house was broken into last week. subject ‘dog’ + string of adjectives + prepositional phrases + embedded sentences

30 Facts syntactic theory must account for: Fact 5 5. Sentences with the same apparent structural elements and word orders can have different meanings or interpretations. 1)John is easy to please 2)John is eager to please Subject verb adjective infinitive On the surface, the structures of sentences 1 and 2 appear to be the same.

31 Facts syntactic theory must account for: Fact 5 1)John is easy to please 2)John is eager to please In sentence 1, John is unspoken/understood object of ‘to please’ subject = ? (somebody In sentence 2, John is unspoken/understood,) subject of ‘to please’ object = ? (somebody)

32 Facts syntactic theory must account for: Fact 6 6. A single sentence may have more than one meaning or interpretation. This is called ambiguity. Structural ambiguity: The two meanings hinge on different underlying relationships between the words in the sentence. Example: Visiting professors can be interesting.

33 Facts syntactic theory must account for: Fact 6 The structural ambiguity of the sentence rests on the ambiguous structure of the phrase visiting professors. [Visiting professors] can be interesting. modifier noun Meaning: Professors who have come here temporarily from other universities. or [Visiting professors] can be interesting. gerund noun Meaning: For someone to visit professors.

34 Facts syntactic theory must account for: Fact 6 Lexical ambiguity: Alternative interpretations of a sentence rest on different meanings of homophonous lexical items. Example: She ate her cottage cheese with relish. ‘relish’ = condiment or enthusiasm. The two words sound identical, but have different meanings.

35 Facts syntactic theory must account for: Fact 7 7.Not all elements of a sentence appear on the surface, yet listeners can correctly interpret the sentence. For example: Joe likes pizza and Jack does too. ‘missing’ element: ‘likes pizza’ Both like pizza, but ‘likes pizza’ appears only once.

36 Facts syntactic theory must account for: Fact 7 Pronouns sometimes stand in for ‘missing’ elements: Mary bought some ice cream and __ ate it. Mary bought some ice cream and she ate it.’ If ‘Mary’ and ‘she’ stand for the same individual, they are co-referenced. It is also possible that ‘she’ is co- referenced with someone else.

37 Facts syntactic theory must account for: Fact 8 8.There are quite strict rules for forming sentences which speakers must adhere to. Syntactically ill-formed sentences are ungrammatical. *Eats the food the child. *Mary refused to allow that the children go to the concert. ✓ Mary refused to allow that type of language.

38 Facts syntactic theory must account for: Fact 9 9.Syntactic and semantic well-formedness are independent of one another. The following sentences aresyntactically well-formed but semantically anomalous or nonsensical: *Colourless green ideas sleep furiously. *A verb crumpled the milk.

39 Transformational/Generative Approach To account for these and other facts, most linguists adopt a transformational generative (TG) approach to describing the syntactic component of grammar. A TG approach emphasizes the search for Universal Grammar (UG).

40 Transformational/Generative Approach UG presupposes that languages operate under a shared set of categories, operations and principles. Although languages obviously differ from one another, their are common principles governing the way they form sentences. These properties of UG are called language universals.

41 Transformational/Generative Approach By using the same descriptive approach for all languages, linguists hope to identify language universals and gain a more complete understanding of UG. At the syntactic level, there are clearly two subcomponents found in all languages: 1. a lexicon 2. a computational system

42 Transformational/Generative Approach The lexicon or mental dictionary lists the words (and morphemes) in a language. The lexicon also includes information about each entry regarding: -pronunciation -meaning -form (root, affix, bound, free, etc.) -syntactic category information? (noun, verb, etc.)

43 Transformational/Generative Approach The computational system includes the operations that allow words to be combined into syntactic structures. The computational system has two major components: Merge Move

44 Transformational/Generative Approach Merge allows the creation of phrases (parts of sentences) and the combining of the these phrases into sentences. Move allows certain elements to be transported to a new position within a sentence. An example of a moved element is the word ‘what’ moving out of object position into sentence initial position in: ‘What are they looking at?’

45 Transformational/Generative Approach We will examine the elements of syntax as follows: 1. The lexicon and the notion of syntactic categories 2. The creation of phrases (phrase structure) 3. The merge operation to form sentences 4. Types of phrasal & clausal complements 5. Move

46 Transformational/Generative Approach Transformational Generative theory has undergone many reformulations over the past 50 years. We are operating with a recent version. Thus you may encounter terms elsewhere that are roughly equivalent to the elements of syntax that we are examining. We will discuss these terms at a later date.

47 The Lexicon/Syntactic Categories There is some controversy in current linguistic theory regarding whether the syntactic category (noun, verb, etc.) of a word is stored or syntactically determined. There are essentially two positions. 1. This information is stored in the lexicon. 2. The syntactic category is only determined when the word enters into a syntactic structure. We will not resolve the issue in this class. We will assume position 1, although the reasoning behind position 2 may be discussed.

48 The Lexicon/Syntactic Categories All languages group their words into syntactic categories. We find remarkably similar syntactic categories across languages Your textbook provides example of the commonly found categories in Table 5.1.1 on page 133.

49

50 The Lexicon/Syntactic Categories The Lexical/Nonlexical distinction is roughly equivalent to the distinction we used in morphology: OpenClass/Content or Lexical Words versus ClosedClass/Function Words or Non-lexical The chart is reproduced in the next slide

51 (Closed Class) Non-lexical/functional Non-lexical/ functional Lexical

52 The Lexicon/Syntactic Categories The classification of words into syntactic categories can rely on: the type of meaning they express what inflectional affixes they take the types of structures they fit into (distribution) Classification relies on a combination of these approaches.

53 Classifying Syntactic Categories We will apply these 3 types of classification in the following slides. This will hopefully allow you to gain a better understanding of Syntactic Categories (aka: parts of speech)

54 Classifying Syntactic Categories Meaning The meanings of Lexical (Open Class/Content) words are generally much easier to define that those of Non-lexical (Closed Class/Function) words. Consider the words: ‘the’ (Non-lexical/Closed Class - determiner) and ‘brush’ (Lexcial/Open Class - noun)

55 ‘the’ versus ‘brush’ It’s easier to explain the function of ‘the’, or where it occurs (before nouns), than what it actually means. It’s easier to describe the concept ‘brush’ than the concept ‘the’.

56 Meanings of the Major Lexical Categories Nouns: name entities –objects (book) –people (Mary) Verbs: designate –actions (eat) –sensations (feel) –states (be, seem) Adjectives: designate properties and attributes of what nouns name (heavy book) Adverbs: Denote properties and attributes of what verbs designate (eat quickly) Adverbs tell us ‘how, why, where, when’.

57 Meanings of the Major Lexical Categories Meaning is not always a clear-cut way of deciding the part of speech of word. Some lexical/content words are more difficult to define. For example, the concepts ‘truth’ or ‘honesty’ do not name entities.

58 Meanings of the Major Lexical Categories Items from two different categories can have similar meanings. For example, the verb ‘hate’ and the noun ‘revulsion’ have very similar meanings: I hate carrots. I feel revulsion toward carrots.

59 Meanings of the Major Lexical Categories Some words, like ‘brush’, can be a noun or a verb. I bought a new brush (noun) for the dog. I brush (verb) the dog every day.

60 Inflections for Determining Major Lexical Categories So we still need to go beyond simple meaning to define a lexical (content) word’s syntactic category. We can also look at what inflections a form takes, as inflections usually attach to a particular part of speech. Note the references to parts of speech in the following list of English inflections.

61 The inflectional affixes of English

62 Inflections for Determining Major Lexical Categories Thus we can tell if ‘ship’ is a noun or a verb by seeing whether it takes affixes that normally attach to a verb or a noun. ‘ship’ + pl. ‘s’ as in: I like to sail on ships. ‘ship’ + poss. ‘s’ as in: The ship’s hull is painted red. So far, it looks as if ‘ship’ is a noun.

63 Inflections for Determining Major Lexical Categories To be certain, lets see if adjectival inflections can be attached to ‘ship’. Comparative ‘er’ as in: * That one is shipper than the first one. Superlative ‘est’ as in: *That is shippest one of all. So ‘ship’ is not an adjective.

64 Inflections for Determining Major Lexical Categories What about verbal inflections? Past tense ‘ed’ as in: They shipped the package last week. Progressive ‘ing’ as in: They are shipping the package by air. So, it looks as if ‘ship’ is a verb as well as a noun.

65 Inflections for Determining Major Lexical Categories In fact, many words can belong to more than one lexical category. For example: brush (noun, verb) comb (noun, verb) near (preposition, verb, adjective) They got bored near the end. They neared the finish line. The are nearer to the end than us.

66 Distribution for Determining Major Lexical Categories We have seen that neither the meaning nor the affix test tells us reliably which lexical category a word belongs to. Another more reliable way of determining lexical category is by looking at a word’s distribution.

67 Distribution for Determining Major Lexical Categories By distribution, we mean the type of elements that a word can co-occur with. The most useful type of elements for distributional analysis are what functional categories a word can be used with, although we can also look at what lexical categories it can be used with.

68 Distribution for Determining Major Lexical Categories For example: nouns occur with determiners such as ‘the’ ‘the dog’ verbs occur with auxiliaries such as ‘will’ ‘will go’ adjectives occur with degree words such as ‘very’ ‘very hot’

69 Distribution for Determining Major Lexical Categories Verbs do not occur with determiners: * the go Nouns do not occur with auxiliaries such as ‘will’ *will lamp Neither nouns nor verbs occur with degree words such as ‘very’ * very lamp’ * very go

70 Homework Study Guide: Page 104 O&A: Page 170-171, Ex. 2 Think about how you could have used distribution, meaning and inflection tests in order to identify the syntactic categories (parts of speech) of the underlined words and words in the sentences of Ex. 2. Refer to Tables 5.1, 5.2 and 5.3 in O&A for help.

71 Distribution for Determining Major Lexical Categories Distributional analysis helps us to see the difference between verbs and auxiliaries. A verb can co-occur with an auxiliary, but a verb cannot co-occur with another verb. We may eat. We have eaten. We are eating. * We play eat.

72 Distribution for Determining Major Lexical Categories Sentences normally have only one verb. So a sentence with more than one verb is really more than one sentence. Such as two conjoined sentences as in ‘They’re moving and grooving.’ From: ‘They’re moving. They’re grooving.’

73 Distribution for Determining Major Lexical Categories Or, two verbs might be a clue that there is a main sentence containing an embedded or subordinate sentence or infinitival complement as in ‘We are going to play.’ ‘go’ is the main verb and ‘play’ is the verb in the infinitival complement ‘to play’.

74 Distribution for Determining Major Lexical Categories Further distributional analysis can show us that there are actually three types of auxiliary in English: Modals (will, would, shall, should, can, could, must, may, might) Perfect (have –en) Progressive (be-ing)

75 Distribution for Determining Major Lexical Categories Lets look at modals first. Modals can co-occur with verbs: He will eat. He may eat. Modals cannot co-occur with modals: * He may will eat.

76 Distribution for Determining Major Lexical Categories You cannot replace a verb with a modal as in * ’We are maying.’ Nor can you replace a modal with a verb as in * ’We wish be eating.’

77 Distribution for Determining Major Lexical Categories Modals can co-occur with perfect ‘have’. He may have eaten. Modals can co-occur with progressive ‘be’. He may be eating. Notice that when modals co-occur with any of these elements, the modal always comes first.

78 Distribution for Determining Major Lexical Categories Lets try a substitution test to determine whether the following are modals or verbs: Try substituting each of the following words for ‘will’ in the following sentence: can, play, could, shall, see He will eat. Which ones are OK?

79 Distribution for Determining Major Lexical Categories Now try substituting the same words for the verb ‘eat’ in ‘He will eat’. can, play, could, shall, see Which ones are OK? So our substitution test tells us that: ‘can’, ‘could’ ‘shall’ are modals ‘play’ and ‘see’ are verbs

80 Distribution for Determining Major Lexical Categories Modals always occur before ‘perfect’ and ‘progressive’ (when they are actually present) and before a ‘verb’. Verbs occur after all possible elements in the auxiliary.

81 Distribution for Determining Major Lexical Categories How do we know that perfect ‘have -en’ is not a modal? Try the substitution test on: He will have eaten. Can you substitute a modal for ‘have’? *He will may eaten? Can you reverse the order of ‘will’ and ‘have”? *He have will eaten?

82 Distribution for Determining Major Lexical Categories How do we know that progressive ‘be -ing’ is not a modal? Try the substitution test on: He will have eaten. * He be having eaten.

83 Distribution for Determining Major Lexical Categories How do we know that progressive ‘be –ing’ and perfect ‘have –en’ are separate categories? Try reversing them in: He may have been eating. * He may be having eaten.

84 Still not convinced about modals? Lets apply the meaning test. Modals express the speaker’s attitude or intentions with respect to the sentence. Modals can express possibility, probability, necessity, intention, etc., as in: I will go. I may go. I must go.

85 Still not convinced about modals? Lets apply the inflection test. Unlike verbs, modals do not take the present tense ‘s’ inflection in the 3 rd person singular verbs. He eats at nine. * He wills eat at nine. * He mays eat at nine.

86 Homework We can apply the distribution and meaning tests to identify perfect and progressive as distinct functional categories. The meanings of sentences with perfect and progressive are affected in interesting ways. Think about the meanings of the sentences with perfect and progressive on the following slide. Be prepared to discuss them in your DGD.

87 Perfect and Progressive John has studied karate, but he is more interested in kickboxing. John had studied karate for ten years before he got his black belt. I lived in Florida for ten years. Then I moved to Texas. I have lived in Florida for ten years, but I still miss Canada. I had lived in Florida for ten years before I saw my first alligator. I can’t talk while I am driving. I didn’t use my cell while I was driving. I am driving to Montreal tomorrow. Think about the concept of tense in English and what it expresses: I am exercising right now.(present progressive - ongoing) I exercise every day. (simple present - habitual) I exercised every day last week.(simple past - completed) I was exercising when you called me last week. (past progressive - ongoing in past)

88 Perfect Perfect have-en expresses the duration of an event as in ‘I have lived in Florida for ten years.’ In the past tense it can also express the duration of an event with respect to a certain point in the past, as in ‘I had lived in Florida for ten years when they discovered I was an illegal alien.’ Perfect have-en can also be used to refer to an event that took place over some indefinite period in the past, even when the sentence is actually inflected for the present, as in ‘I have studied karate’. Perfect have-en is rarely used to indicate a completed act. Instead English uses the simple past tense as in ‘I lived in Florida for ten years.’ Compare that to the sense of duration in ‘I have lived in Florida for 10 years.’ Note also that the simple present in English cannot express duration as in *I know John for ten years. However, the simple present in English does express habitual actions as in ‘I eat breakfast at seven.’

89 Progressive Progressive be-ing refers to events in progress in either the present or the past. In the present, the event is understood as happening while the sentence is being uttered. In the past, the event is understood as happening while another event in the discourse was happening. Progressive can also communicate anticipation of an event which will happen as in ‘I am going shopping later.’ There is a narrative discourse style in English that uses the present progressive and the simple present to relate events that occurred in the story, as in ‘I’m walking down the street last night and this guy jumps out from behind a parked car and starts yelling at me (etc.)’

90 A word about auxiliaries English has four different functional categories that can be described as auxiliaries: tense, modal, perfect, progressive If modal, perfect and progressive are all in a sentence, they must occur in that specific order for the sentence to be grammatical. We will discuss tense placement later.

91 From Word Categories to Phrases Sentences are made up of sub-parts called phrases. Every language has a set of rules for forming these phrases. They are called Phrase Structure Rules The Phrase Structure Rules are a set of rules that allow us to map out the structures of phrases in a language. We diagram these structures as inverted trees.

92 From Word Categories to Phrases The inverted trees reflect the hierarchical arrangement of phrases. Sentences consist of a series of phrases also joined together in a hierarchical manner.

93 Merge: X’ (X-bar) Merge is the part of the syntax in which of words are fitted together into phrases and in which phrases are joined together to form sentences. Merge combines words into phrases using the X’ schema that we will be discussing shortly. The Phrase Structure Rules determining these phrases used to be fairly elaborate, but in the current formulation of the theory have been essentially streamlined to the X’ schema.

94 Merge: Subcategorization Phrases are also the product of an interaction between the X’ schema and the subcategorization properties of words. Subcategorization refers to the type of complement structures that certain words must or can appear with. ‘to hate’ (verb) requires a direct object *I hate. I hate carrots.

95 I hate carrots.

96 Merge: D-structure Merge results in what used to be called the Deep (D) Structure of a sentence The D-structure of a sentence very closely resembles the canonical word order in the language. D structure is not, however, the final form of the sentence.

97 Move Not all sentences have the canonical word order in the language. Thus another component of syntax, called Move, moves elements to where they belong in the surface structure or S- structure of the sentence. Compare: John is eating an apple. (canonical) Is John eating an apple? (non-canonical)

98 Why D- and Surface Structure? We just saw that not all sentences follow canonical word order. But why not allow Merge to create these structures in the first place? Why do we need Move? I will provide some reasons in the next few slides and point out others as we explore the syntax more thoroughly.

99 Why D- and Surface Structure? By adhering to strict canonical word order, D- structure gives us important information about the semantic roles of the elements in a sentences, especially the main nouns with respect to the verb. Thus, for English, the first Noun Phrase constituent in the tree represents the subject of the sentence. The subject of the sentence has a special relationship to the verb, as it is the doer of the action or agent.

100 Why D- and Surface Structure? The first Noun Phrase immediately following a transitive verb is its direct object or theme. In semantics, these relationships of nouns with respect to verbs and their subjects and objects are called thematic roles. The students read the book. agent theme

101 Why D- and Surface Structure? The thematic roles of the constituents of the sentence would not be so apparent at D-structure if non-canonically ordered trees were permitted. The move component of the syntax can operate on D-structure trees to create these non-canonical orders as required.

102 Why D- and Surface Structure? At D-structure it is clear when two sentences have the same thematic relationships between their words. Recall the sentences we looked at a few classes ago:

103 Why D- and Surface Structure? declarative: Everyone is happy. (verb) yes/no question: Is everyone happy? (verb)

104 Why D- and Surface Structure? Wh question: What are they looking at? object theme Declarative: They are looking at what. object » theme

105 Why D- and Surface Structure? scrambled order: The boy gave the toy to the girl. direct indirect object themegoal The boy gave the girl the toy. indirect direct goal theme

106 Why D- and Surface Structure? By having the alternative word orders created by Move, there is no need for extra phrase structure rules that would create essentially the same structure in two different places in the tree. So we don’t need a rule in Merge permitting a verb to occur at the beginning of a tree as well as after the subject: Is everyone happy? Everyone is happy. We also don’t risk confusion about whether the role of the nouns ‘everyone’ and ‘what’ in the question sentences.

107 A schematic of syntax Merge Deep Structure Move Syntactic Surface Structure

108 Is that all there is to the grammar? In the previous slide we saw that Merge creates D-structure which is acted upon by Move which in turn creates Syntactic Surface Structure. Is that it for the grammar? No. The syntactic surface structure does not represent the final spoken form of the utterance. The rules of phonology and semantic interpretation (logical form) must apply before the sentence is fully derived.

109 From theory to practice Merge is the product of the X’ schema. This basically sets out the structure of a typical, generic phrase as: » XP (Specifier)X’ X(complement)

110 From theory to practice The abbreviations in the generic X’ phrase structure tree X=part of speech of the head of the phrase P=phrase (e.g. NP = noun phrase) Specifier=phrase boundary marker, makes meaning of head more precise Complement=phrases which provide information about the meaning of the head. The type of complement a head can take is part of the information stored with it in the mental lexicon. NB: Parentheses ( ) mean that an element is optional in some phrases and with some heads.

111 Types of X - Heads Heads can be: Nouns, Verbs, Adjectives, Prepositions At the sentence level, heads are called: I = InflectionC= Complementizer We will discuss sentence heads later.

112 Specifiers (abbreviations in bold) The following can act as Specifiers: Determiners (for nouns N): e.g. ‘the, a, this, these, those, no,’ Adverbs (for verbs V): e.g. ‘never, perhaps, often, always Degree word (for Adjectives A, Prepositions P) e.g. ‘very, quite, more, almost’

113 Complements Phrases that add information about entities and locations implied by the head and for which the head is subcategorized. In the following example, the NP ‘carrots’ is the complement of the verb ‘hate’. ‘to hate’ requires a direct object complement *I hate. I hate carrots.

114 Other Complement Examples prepositional phrases as in: 1.I often eat [at that restaurant]. 2.I never approved [of that purchase]. 3.I was certain [of his loyalty]. 4.The destruction [of the city] angered me. 1 and 2 show verb complements, 3 shows an adjective complement. 4 shows a noun complement.

115 Practice drawing phrase structures Keep in mind that all phrases follow the x’ schema. XP (Specifier)X’ X(complement)

116

117

118 He often reads tons [of books]

119

120 He [often reads tons of books]

121 How to recognize a phrase Look for typical heads, such as: noun, verb, adjective, preposition Work from right to left, since English branches right and your lowest phrases in the tree will likely be found to the right. Consider possible structures of phrase and see how X’ applies

122 Complements N B: See O&A Charts 5.5 (p143), 5.6, 5.7, 5.8 (p144) for types of complements

123 Verb Complements

124 Noun, adjective, preposition complements

125 Phrase Tests You can also try the phrase tests of: substitution movement coordination

126 Substitution Test nouns can be replaced by ‘they’ ‘it’ [The boys] bought [a firecracker]. verbs can be replaced by ‘do so’ The children can [play]. prepositional phrase can be replaced by ‘there’ He went [to the bank].

127 Movement Test prepositional phrases can often be moved without compromising the grammaticality of the sentence The children sang [in the chapel]. [In the chapel] the children sang.

128 Coordination Test a phrase can be conjoined with another phrase of the same type using ‘and’ They [mowed the lawn]. They [mowed the lawn] and [raked the leaves].

129 Sally saw the car on the hill. - ‘hill’ is a noun, so it must be part of an NP -‘the’ is determiner, so it must be the specifier of the NP ‘the hill’

130 Sally saw the car on [the hill].

131 Sally saw the car on the hill. -‘on’ is a preposition, which is the head of a PP -PPs have NPs as their complement, so ‘the hill’ is the complement of the PP with ‘of’.

132 Sally saw the car [on the hill].

133 Sally saw the car on the hill. -‘car’ is a noun, so it must be the head of an NP -‘the’ is a determiner, so it must be the specifier of the NP with ‘car’ -‘on the hill’ is a PP which acts as a complement to ‘car’

134 Sally saw [the car on the hill].

135 Sally saw the car on the hill. -’saw’ is a verb, which acts as the head of a VP -’saw’ is subcategorized for an NP complement -the NP complement of ‘saw’ is ‘the car…’

136 Sally [saw the car on the hill].

137 Sally saw the car on the hill. ’Sally’ is a noun, which is the head of an NP

138 [Sally] saw the car on the hill.

139 But how does it all fit together? Using X’, the theory treats the subject NP as the specifier of a new phrase called IP The theory treats VP of the sentence as the complement of this phrase. The head of the phrase is the tense inflection of the sentence I. Remember that English has only two tenses: past (+pst) present (-pst)

140 Sally saw the car on the hill.

141 Try: The dog bit the cat.

143 IP IP allows us to deal with the tense and modal parts of the auxiliary of the sentence. The remaining parts of the auxiliary (perfect ‘have’ and progressive ‘be’) are handled a little differently, as we will see.

144 Modals in IP The theory treats models has the lexical part of I of the IP. This is because models have inherent tense. We never add a tense inflection to make them past or present. He will eat. (-pst, NB: no ‘s’ in 3 rd pers. sg.) He would eat if he had money (-pst) He would eat whenever anyone fed him. (+pst)

145 Modals in IP You judge the tense of the modal based on the rest of the sentence or discourse. If there is a modal, the verb is not marked for tense. The dog will bite the cat. The dog bites the cat.

146 Modals in IP Note that if there is no Modal, the tense in the PS tree matches the inflection on the verb. This may seem bizarre, but syntactic theory has had a long-standing conflict of over whether and how to handle inflectional morphology. Compare:

149 Modals in IP Any modal could take the place of ‘will’ in ‘The dog will bite the cat’. The dog will bite the cat. The dog would bite the cat. The dog may bite the cat. The dog can bite the cat. The dog could bite the cat. The dog should bite the cat. The dog must bite the cat. The dog might bite the cat. The dog shall bite the cat.

150 Perfect and Progressive If the sentence contains the auxiliaries perfect or progressive or both, these are treated as verbs. This will give us successive VPs as follows:

151 1 2

152 Modal, Perfect and Progressive In ‘The dog has bitten the cat’, note that tense is on perfect ‘have’, not on the verb. Tense with perfect ‘have’ is relative to the other events in the discourse. Compare a sentence with modal and perfect. The dog will have bitten the cat. Here tense is expressed through modal ‘will’, rather than on ‘have’.

156 Modal-Perfect-Progressive In older versions of the theory, the affixes associated with perfect ‘have’ (-en) and progressive ‘be (-ing) were shown together with them as unattached inflections in the PS. Movement took place to attach them where they belonged. Nowadays, syntacticians do not want morphological operations within syntax. Thus they are glossed over in the PS trees.

157 Whole Sentences as Complements What if our complement is a whole sentence embedded in the bigger sentence. We use the term clause for sentence. Hence – embedded clause. A clause must have a verb.

158 Embedded Clauses I know [ that Mary has left ]. Compare it to: I know [the answer]. The [ ] structures are both complements of the verb, but one is a clause (aka: sentence). The embedded clause acts like an NP.

159 Embedded Clauses Embedded clauses that replace NPs are marked by the words ‘that’ or ‘whether’ or ‘if’. These are called complementizers. They form the head of a CP (complementizer phrase) that goes into the complement position of the VP.
