1 Introducing Lexical Relations By:Arsalan Ali QadirShaswar Kamal Mahmud12th of November 2011
2 What‘s Lexical Relations? The Definition:A lexical relation is a culturally recognized pattern of association that exists between lexical units in a language.Why it’s important?Not only can words be treated as ‘ containers’ or as fulfilling ‘roles’, they can also have ‘relationships’. In every day talk, we frequently give the meanings of words in terms of their relationships.conceal = hideshallow X deepDaffodil as “it’s a kind of flower”
3 Lexical Relations There are 2 fundamental types of sense relations: Paradigmatic: A paradigmatic relationship is one where an individual item may be replaced by another. Paradigmatic – reflect semantic choices available (within a lexical field): a bottle of __(milk/juice/beer, etc)Syntagmatic: A syntagmatic relationship is one where signs occur in sequence or parallel and operate together to create meaning. It’s the relation between linguistic items in a sentence.
4 4 basic relations between classes: Congruence Relations4 basic relations between classes:IdentityInclusionOverlapDisjunction
5 example: he plays violin <-> he plays fiddle Congruence Relations~identity: SynonymyDifferent lexemes have the same or similar meaningSynonyms occur due to different dialects or different origins (cloth OE &Fabric Lat)X and Y are cognitive synonyms if- they are syntacticly identical.- S1 containing X has the same truth-conditions as anidentical sentence S2 in which X is replaced by Y.example: he plays violin <-> he plays fiddle
6 Congruence Relations ~inclusion:Hyponymy When the meaning of one form is included in the meaning of another. X is a kind of Y.Hyponymy is a relation of inclusion. A hyponym indicates the meaning of a more general word.dog and cat are hyponyms of animalsister and mother are hyponyms of women.There is hierarchical relationship. In ‘hyponymy’, the higher level terms are called superordinates or hypernym, while the lower level terms are called hyponyms. In addition, two or more words that share the same superordinate term are co-hyponyms.
7 ~inclusion:Hyponymy Congruence Relations There is hierarchical relationship. In ‘hyponymy’, the higher level terms are called superordinates or hypernym, while the lower level terms are called hyponyms. In addition, two or more words that share the same superordinate term are co-hyponyms.Example: Music (superordinate= hypernym)pop jazz hip hop (hypnyms & cohyponyms)
8 this is a dog / this is a pet Congruence Relations~overlap: Compatibilityoverlap : E1 and E2 have a non-empty intersection, but one is not included in the other,A pair of compatibles must have a common superordinate.this is a dog / this is a pet
9 this is a dog vs. this is a cat Congruence Relations~disjunction : IncompatibilityE1 and E2 have no element in common.this is a dog vs. this is a catAB
10 Partial relations Partial relations Quasi-relations = relations between lexical items which don't always occur at the same place in a sentence, i.e. which aren't exactly syntacticly the same.Example: „finish“ and „complete“Quasi-relations= relations between lexical items which meet the semantic requirements, but are of different syntactic categoryExample: „it is red/yellow/green“ with „it is coloured“ as quasi-superordinate.
11 Partial relations Pseudo-relations Para-relations = 2 lexical items do not stand in any relation, but under certain circumstances they show one or more characteristics of a certain relation.Example: „This triangle has 3 equal sides“ and „This triangle has 3 equal angles“.Para-relations= relations between lexical items which are expected rather than necessaryExample: „dog“ and „pet“. -It‘s a dog, but it`s a pet.
12 HomonymyHomonymy is a lexical relation where ‘one form (written or spoken) has two or more unrelated meanings’ .Words of this type are called homonyms. For example,bank (of a river) – bank (financial institution)bat (flying creature) – bat (used in sports)race (contest of speed) – race (ethnic group)Homonyms are words that have separate histories and meanings, but have accidentally come to have exactly the same form.
13 meat/meet, flour/flower, right/write, to/too/two, leek/leak. HomonymyHomophonyHomophony is a lexical relation where ‘two or more different (written) forms have the same pronunciation’ .meat/meet, flour/flower, right/write, to/too/two, leek/leak.Homophones usually ‘have unrelated meanings and different spellings but have the same pronunciation’.
14 HomonymyHomographyHomography is a lexical relation where words are ‘pronounced differently but spelt the same’).For example, a live concert, but where do you live?; a lead pipe, but a lead singer.These are called homographs (literally ‘same writing’).
15 PolysemyPolysemyUnlike word of the ‘homonymy’ relationship, some words with the same form do have related meanings, and these words are very common in English.Polysemy can be defined as one form (written or spoken) having multiple meanings that are all related by extension.head, ( of your body, person at the top of a company or department)foot (of person, of bed, of mountain).run (person does, water does).
16 PrototypePrototypeThe concept of a ‘prototype’ is usually interpreted as the ‘clearest example’, or ‘exemplar’ of certain words.English native speakers might wonder if ostrich and penguin should be hyponyms of bird, but have no trouble with pigeon.Reem , Amana (kind of bus) , Sardi ( all cold drinks)
17 MetonymyMetonymyThis word relation can be ‘based on a container-contents relation (bottle/water, can/juice), a whole-part relation (car/wheels, house/roof) or a representative-symbol relationship (king/crown, the President/the White House).Unlike ‘hyponymy’, which is a ‘kind of’ relation, ‘metonymy’ is a ‘part of’ relation.
18 MetonymyThis ‘part of’ relation can also be represented by a hierarchy of super-ordinate and subordinate (meronym) terms.For example:Plantflowers stempetal stamen
19 AnomalyAnomalyAnomaly means irregularity. It is a concept that has been used in many other disciplines, such as astronomy, geophysics, medicine, and religion.It is also used in linguistics (particularly in semantics) referring to ‘meaninglessness’.Anomaly is a ‘deviation from normal semantic rules to create ‘nonsense’ of something irregular, contradictory.A famous example of anomaly (meaninglessness) is ‘Colorless green ideas sleep furiously’ by Noam Chomsky.
20 Time is money Life is a journey MetaphorMetaphorMetaphor (from the Greek: metapherin) is language that directly compares seemingly unrelated subjects. More generally, a metaphor describes a first subject as being or equal to a second subject in some way.Metaphors usually allow people to understand one thing as another, without getting confusedTime is money Life is a journeyA metaphor is usually contrasted with a ‘simile’. A simile is a comparison of two unlike things, typically marked by use of ‘like’, ‘as’, ‘than’…The fog was as thick as pea soup Madder than a bull
21 IdiomsIdiomsAn idiom is an expression (i.e., term or phrase) whose meaning cannot be deduced from the literal definitions and the arrangement of its parts. But refers instead to a figurative meaning that is known only through common use.kick the bucket = To die.dog eat dog (a situation of fierce competition in which people are willing to harm each other in order to succeed).Idioms require some foundational knowledge, information, or experience, to use only within a culture and they are not considered an official part of the language, but rather a part of the culture.
