Semantics Is…
The study of meaning in language.It deals with the meaning of words (lexical semantics).And how meaning of sentences (compositional semantics) is derived from words.

Principle of Compositionality
The principle stating that the meaning of a sentence is determined by the meaning of its words and by the syntactic structure in which they are combined. AKA: Frege’s principle (Gottlob Frege)

Lexical vs. Compositional SemanticsLEXICALman: 2-legged mammal, (relatively) hairless, male sex, dog: 4-legged mammal, hairy, canine, definitely loyal
COMPOSITIONALDog bites man. (happens all the time; not too interesting)Man bites dog. (newsworthy)

Language: A multifaceted phenomenon!
Language meaning communicates information about the world around us (language as a system of symbols) Symbols are things that stand for or refer to other
things. Language with information content.
Meaning is processed in the mind of the speaker/hearer (that is, cognitive & psychological).
Meaning is a social phenomenon (contexts important)
Meaning of words/sentences have various relationships among themselves (antonyms, synonyms, etc.) (can be studied independently)

THEORIES OF MEANING
Four theories to the meaning of words: Dictionary meanings Mental image Referents Componential

Dictionary Meanings
demand (N) the need or desire that people have for
particular goods or services
desire (N) a strong hope or wish
wish (N) the act of wishing for something
wish (V) to hope that something will happen

Problems with dictionary meanings
Understanding meaning of word involves understanding all the words in definitionCircularity pride: the quality or state of being
proud proud: feeling or showing pride

More problems with dictionary meanings:
They are NOT theoretical claims about the nature of meaning, but a practical aid to people who already speak a language. They are usually paraphrases.They may be a way of learning the meaning of some words, but there is much more to word meaning than the dictionary definition. Why?

Mental image…Is a graphic representation in one’s mind of a referent (when I say table, you "draw" a table in your mind)There is much more to meaning than a simple mental image. Why? People may have very different mental images for
same word (lecture – from perspective of student vs. teacher)
Some words, even though having meaning, have no real definite image (honesty, or the)
Mental images are usually a prototype or standard of the referent (bird: what bird? -- image may exclude atypical examples)

What is the prototype for bird?

Advantages of prototype theory
Provides some insight into the way we conceive of certain ideas/objectsEvidence from experimental psychology reaction time: typical member <
atypical member
Prototypes may help children learn the meanings of new words

Disadvantages of prototype theory
Culturally and socially dependent. prototypes can vary across
populations.
Many words have no clear mental images. forget, things, without, concept, …..

Referents…
Have to do with the fact that words usually stand for (refer to) actual objects or relations in the world. Example: “Dubya”, “Florida”, “Disney World.”
There is much more to meaning than a referent. Why? It would exclude from language fantasies, speculations,
and fiction.(Santa Claus refers to what?).
The fact that two words (or expressions) refer to the same thing does not indicate that they mean the same thing.(Queen Elizabeth = Queen of England in 2005?).
What referents do these words have: forget, the, some…?

Componential Theory
The meaning of a word is specified by smaller semantic componentsSemantic components are primitive elements of meaning expressed as binary features (+ or -)
![Page 17: Semantics The Study of Meaning in Language. Semantics Is … The study of meaning in language. It deals with the meaning of words (lexical semantics). And](https://reader035.vdocuments.us/reader035/viewer/2022062300/56649d975503460f94a808ac/html5/thumbnails/17.jpg)
Semantic decomposition

man:[+ human][- female][+ adult]
girl:[+ human][+ female][- adult]
boy:[+ human][- female][- adult]

Advantages of componential theory
Captures similarities among semantically related wordsGroups meanings into natural classes (like phonology)

Disadvantages of componential theory
Difficult to analyze abstract concepts What are the semantic components of
blue? [+ color]? [+ blueness]?
Meaning of semantic components is sometimes no more explanatory than the words they are specifying

Meaning relationshipsWithin Lexical Semantics
There are many ways for words to be related: Morphologically
lift ~ lifted (same stem) Syntactically
call ~ take (both transitive verbs) Phonologically
knight ~ night (both [] Semantically

Semantic relationships
Semantic relationships indicate a similarity in meaning between two words. “crayon” and “pencil.” But not “pencil” and
“refrigerator”, for example.

The semantic relationships we will discuss here are: Hyponymy Synonymy Antonymy Scalar/gradable pairs
