1The Phenomenon of Stress Metical Principles and Parameters Lecture 6The Phenomenon of StressMetical Principles and Parameters
2Syllable Prominence Some words can be pronounced in one of two ways: Nouns VerbsINcrease inCREASeCONtest conTESTCONtrast conTRASTIMplant imPLANTGrammatical difference goes hand in hand with a difference in location of the word’s highest prominence.The prominence in question is what we call STRESS.Thus, one of the syllables of each English word is singled out as the stress carrier.
3Word ProminenceOne of two words in a sequence is more prominent than the other:time FLIES TIME-fliesA hierarchical structure is superimposed on syllables and words.This is functionally analogous to the prosodic structure that gathers segments into syllables.
4Metrical GridsThe metical grid is the formal notation for the representation of the prosodic structure and consequently for stress:a * b * Stress line* * * * Baseline(to) implant (an) implant* * Stress line* * * * Baselinetime flies time-flies
5BaselineIn the baseline, all and only the segments that qualify to bear stress are marked with an asterisk.Those are normally the syllable heads.The syllable head constitutes the core of the syllable; it is its sonority peak.
6Stress lineIn contrast to the stress potential formalized by the baseline, the stress line signals the actual presence of stress on an element.Stress can be interpreted as the projection of certain syllable heads onto a higher structural level.
7Stress MovementIn English double names, the second name is more prominent:* Stress line 1* * BaselineSue AnnWhen a surname follows, main stress falls on the right-most item. However, of the preceding two, the first is now more prominent:* Stress line 2* * Stress line 1* * * BaselineSue Ann CookWhy?
8ClashWhat would the grid structure look like if Ann, rather than Sue, had a line 1 mark?* Stress line 2* * Stress line 1* * * BaselineSue Ann CookThis grid contains a stress clash. There are two adjacent asterisks on stress line 1 that are not separated by an asterisk in the immediately lower level.
9The Rhythm RuleEnglish, among other languages, strongly resists clash.A stress clash is usually resolved by movement:* Stress line 2* * Stress line 1* * * BaselineSue Ann CookStress movement of this kind is generally seen as a result of the Rhythm Rule:* * * ** * * * * *The left-most of the clashing asterisks moves back by one position.
10Retraction Stress retraction is impelled by clash: * Stress line 1 * * Baselineantique* * Stress line 2* * * * Stress line 1* * * * * * Baselineantique chair antique chair
11Retraction FailuresPhrases like antique chair, with stress retraction, strikingly contrast with compounds like antique dealer, with no retraction in spite of the clash:* Stress line 2* * Stress line 1* * * * Baselineantique dealerWhy?
12GapNotice what will happen if antique underwent stress retraction in the compound antique dealer:* * Stress line 2* * * * Stress line 1* * * * * * * * Baselineantique dealer antique dealerThe retraction created a gap in the asterisk column on ti.
13Continuous Column Constraint Metrical grid columns must be continuous; they cannot have gaps.This requirement is formulated in the universal Continuous Column Constraint:Continuous Column ConstraintMetrical grid columns must be continuous.This justifies the retraction failure in antique dealer.
14Retraction FailuresStress clash also persists in constructions like sports contest:* Stress line 2* * Stress line 1* * * Baselinesports contestWhy?
15MovementStress movement could be carried out in contest without contravening the Continuous Column Constraint:* Stress line 2* * Stress line 1* * * Baselinesports contestThe output of this operation is, however, illegitimate in English, where the Rhythm Rule only implements leftward movement.
16Evidence for Stress /t/ weakening Consider the following forms:(a) (b) (c)cutting mastery attainwaiting after retort/  Two conditions for /t/ weakening:- intervocalic- a stressless following vowelt or / [-consonantal] _____ [-consonantal]condition: the second [-consonantal] does not support a gird column
17Evidence for Stress Aspiration Consider the following forms: the voiceless stops in A and B are aspirated, but they are not in C and D:A B C Dtone append stone tomatokin entail skin canoeEnglish voiceless stops are aspirated when initial in a stressed syllable.
18SoThere is a hierarchy of prominence among syllables in words and among words in compounds and phrases.This prominence hierarchy is grounded in rhythm.The drive to preserve rhythm can induce stress movement.
19Stress on the EdgeWe saw that in English phrasal collocations main stress falls on the right, whereas in binary compounds the greatest prominence tends to be on the left.This cross-linguistic tendency is formalized as follows:END STRESSProject the right-most/left-most asterisk
20Phrasal CollocationsPhrasal stress can be assigned by applying End Stress in its “right-most” setting:* Stress line 1* * * * Baselinetime flies time fliesEnd Stress [Right]The last baseline asterisk projects onto the newly created line 1.The resulting grid appropriately expresses the fact that flies has greater prominence than time.
21CompoundsApplying the same procedure to the compound time-flies produces an identical output.Such an output is unattested, however, since we know that the first word is more prominent in compounds.We need to introduce some change in the procedure.
22Multiple Settings?One possible way to get the correct stress in compounds would simply be to switch the setting of End Stress:* Stress line 1* * * * Baselinetime-flies time-fliesEnd Stress [Left]This procedure is rejected on the grounds that it requires multiple settings for the same parameter in a single language.
23ExtrametricalityAn alternative procedure, consistent with the “right-most” setting of End Stress involves concealing the right-most asterisk.The device known as Extrametricality excludes the element it acts upon from the computations in the metrical grid:Extrametricality:Mark the right-most/left-most asterisk extrametrical.(* <*>)
24PeripheralityExtrametrical behaviour has been found to be associated with peripheral elements.This is formalized as follows:Peripherality ConditionOnly peripheral elements can be extrametrical.
25Compounds and Extrametricality So far, extrametricality is only relevant to compound structures:* * * <*> Baselinetime-flies time-fliesExtrametricalityThe output includes only one baseline asterisk:* Stress line 1* <*> * <*> BaselineEnd Stress [Right]The action of End Stress [Right] places the main stress in the correct position.
26OrderingThe last baseline asterisk in compounds is a potential target for both:- End Stress [Right] and- Extrametricality [Right]Unless Extrametricality applies first, a formally ambiguous output is created:* * Stress line 1* * * * * <*> Baselinetime-flies time-flies time-fliesEnd Stress [Right] ExtrametricalityTherefore, the interaction between the two procedures needs to be regulated.
27Extrinsic OrderingWe could simply stipulate that Extrametricality applies before End Stress.However, this is an example of the disfavoured Extrinsic Ordering, in which the order of rules is stipulated by the analyst instead of being derived from universal principles.
28Restricted Environment The two rules function as follows:End Stress ExtrametricalityInput right-most asterisk right-most asteriskEffect project mark extrametricalEnvironment no context compoundsThe environment of Extrametricality is more restricted than that of End Stress.
29Elsewhere ConditionThe Elsewhere Condition, which is active throughout phonology, regulates the application of the two rules:Elsewhere ConditionGiven two rules such that:(i) their inputs are identical(ii) their outputs are incompatible(iii) the environment of one rule is the same as the environment of the other rule plus something extrathen, the rule with the richer environment is ordered first, and, if it does apply, the other rule is skipped.As a consequence of the Elsewhere Condition, Extrametricality applies before End Stress.
30English Nouns Consider the following two groups of forms: cínema aspáragusélephant metamórphosiscústomer hippopótamusEnglish noun stress is antepenultimate.
31Metrical ProceduresCan we achieve this antepenultimate stress using the metrical procedures available at present?* Stress line 1* * * * * * * * *<*> * * * *<*> Baselinehippopotamus hippopotamus hippopotamusThe output *hippopotámus does not match the correct pattern.
32RhythmEnglish is one of those languages that favour stress in alternate syllables:lá la lá la lá la (S - W)Other languages may achieve this alternating rhythm differently:la lá la lá la lá (W - S)Languages with alternating stress employ one of these two opposite metrical patterns.
33The Metrical FootThe pairing of (S - W) or (W - S) syllables is formally called a FOOT.Binarity can be a property of metrical feet, where each is made up of precisely two elements (syllables).The strong element in the foot is the Head.So, our metrical machinery is augmented with:* Stress line 1- left-headed foot = (S W) (* *) Baseline- right-headed foot = (W S) (* *) BaselineThe location of the foot head is indicated by means of an asterisk in line 1.
34Main Word Stress in English English noun stress algorithm:a. Mark the last element extrametricalb. Build a left-headed foot at the right edge* Stress line 1* * * * * * *<*> * (* *)<*> Baselineasparagus asparagus asparagus(a) (b)As a result of these two steps, main stress is correctly assigned to the syllable pa.
35Verbs and Adjectives implicit implicit implicit The English noun stress algorithm works well for both nouns and suffixed adjectives (médicine - medícinal).However, it does not yield the correct stress pattern for verbs and unsuffixed adjectives (devélop - implícit):* Stress line 1* * * * *<*> (* *)<*> Baselineimplicit implicit implicit(a) (b)The output *ímplicit does not match the correct pattern.
36Restricting Extrametricality To get the correct stress pattern for verbs and unsuffixed adjectives, extrametricality should be suppressed:* Stress line 1* * * * (* *) Baselineimplicit implicitFootingRestricting extrametricality to nouns justifies the difference of stress patterns in English verbs and nouns.
37Unreduced VowelsThe procedure developed so far yields one (left-headed) foot per word.This could be interpreted as one stressed syllable per word.We know that unstressed short vowels in English undergo reduction.However, there are some words with more than one unreduced vowel (hippopotamus).The fact that short vowels surface unreduced suggests that they are stressed.
38Rhythm and Multiple Stress The unreduced vowels are located at equal intervals to the left of the vowel stressed by the algorithm:hamamelidánthemumThe basic rhythm of English involves an alternation of strong and weak elements throughout the word, not just at the right edge.This means that foot construction must sweep across the whole word.
39Multiple Foot Construction * * * * * * <*> baselineh a m a m e l i d a n t h e m u m footing* Stress line 1* * * * (* *) <*> baseline* * Stress line 1* * (* *) (* *) <*> baseline* * * Stress line 1(* *) (* *)(* *) <*> baselineh a m a m e l i d a n t h e m u m
40Secondary Stresses Foot construction iterates from right-to-left. As a result, a number of syllables end up supporting foot heads.Therefore, their vowels do not reduce.These additional peaks of prominence are referred to as Secondary Stresses.Hence, the foot construction rule is modified as follows:b’. Build left-headed feet iteratively from right to left(The direction of footing needs to be stipulated language by language.)
41Word HeadednessWe have a number of left-headed feet in (hama)(meli)(danthe)<mum>.We know intuitively that stress on dan is the strongest.But, there is no structural difference between this syllable and the two other foot heads: ha and me.
42Word HeadednessTo make up for this shortfall, we submit the final footing output to End Stress [Right]:* Stress line 2* * * Stress line 1(* *) (* *)(* *) <*> Baselineh a m a m e l i d a n t h e m u mThe head of the metrical word shows up as the word’s main stress, and the heads of the remaining feet as secondary stresses.
43Summing upA limited set of universal principles and parameters can account for the apparently varied and unpredictable stress patterns of English.Marking an element extrametrical accounts for contrasting stress patterns, while maintaining a single setting for the End Stress rule.Extrametricality is controlled by the Peripherality Condition.Introducing the Foot as a level of analysis allows for assigning correct stress patterns in words made up of more than two syllables.Metrical feet are further substantiated by the alternating patterns of stressed and unstressed syllables.The inventory of metrical parameters includes:the location of the foot’s head,the direction of foot construction,the presence and edge setting of extrametricality, andthe edge setting of End Stress.
