Semantics

SemanticsThe meaning of language

Semantics So far we have considered language from a

structural perspective, with relatively little concern for meaning.

But (obviously) words, phrases and sentences mean something.

Questions in Semantics Why does a certain set of words mean

something and a similar set mean something very different?

When do two different sentences mean the same thing?

How can one sentence mean more than one thing?

What is meaning?

Dictionary DefinitionsIs a word’s meaning simply its dictionary

definition?

Is a word’s meaning simply its dictionary definition? No! In our society, many people feel that the

dictionary definition of a word more accurately represents a word’s meaning than an individual speaker’s understanding of the word.

But descriptivists arrive at their definitions by studying the ways speakers of the language use different words.

That is to say, A word’s meaning is determined by the

people who use that word, not by a dictionary.

Also, dictionary definitions are circular: For the same reason, the meaning of a word

in your mental lexicon can’t just be a string of other words: clearly there must be something more to the meanings of a language’s words.

This will mean the end of my career. I mean to help if I can Wear your uniform properly! This means

you. His losing his job means that he will have to

look for a new one. Black Label means fine whisky. Those clouds mean rain. She doesn’t mean what she said. The Linguistics teacher is mean!

What do words mean?

Mental Images What else is there? One possibility is that a word’s meaning

includes a mental image: when you hear tree, for example, an image (or smell, or whatever) of a tree comes to mind.

Note that a mental image can’t be all there is to meaning, either, as each individual’s mental image of a given thing is likely to be different.

For example: Write down the first example of each of

the following things that comes to mind.

bird vegetable fruit

If that worked… Any analysis of a given word must take

into account this tendency (which is cultural) to choose a typical or ideal example of the kind of thing.

Any word, however, can be used to represent a wide range of things, any one of which may or may not be typical.◦ Even though your mental image of bird may

be, say, a chicken, the word is of course equally applicable to ostriches and penguins.

arm chair and a sofa?

Meaning and Reference So, we need more for a word’s meaning

than simply a definition and a mental image.

Language is used to talk about things in the world, and many words seem to stand for (or refer to) actual objects or relations in the world.

Denotation vs. Connotation

Meaning and Reference It seems reasonable, then, to consider the

actual thing a word refers to, its referent, as one aspect of the word’s meaning.

Note that words can also refer to things that don’t exist in the real world, like Santa Claus, Harry Potter, unicorns etc.

Reference◦ Words always refer to a specific object in the real

world. Joe who is a funny guy is my friend. The funny guy. My friend. That guy.

Lexical Semantics

Joe

The funny guy

My friendThat guy

Problems with Reference Consider the fact that these two sentences

mean the same thing:Bill Clinton is married to Hillary Clinton.The winner of the 1992 U.S. presidential

election is married to Hillary Clinton. So Bill Clinton and the winner of the 1992

U.S. presidential election both refer to the same thing.

Sense (connotation) If reference were meaning alone there

would be some problems: Hobbits, unicorns, of, by, will, may Two expressions that refer to same object,

but different meaning Prime minister & Abhisit Sense but no referent

Lexical Semantics

Summary1. Meaning is provided by a community of

language speakers, not by some special authority like a dictionary or grammar book.

2. The meaning of a word or expression is not just a definition composed of more words in the same language, since ultimately the meaning of some words would have to be known in order to understand the definitions.

Summary3. The meaning of a word or expression is

not just a mental image, since mental images seem to vary from person to person more than meaning does.

4. The meaning of a word involves more than just the actual thing the word refers to, since not all expressions have real-world referents, and substituting expressions with identical referents can change meaning.

IdiomsTwo central features of idioms:

1. The meaning of the idiomatic expression cannot be deduced by examining the meanings of its parts.

2. The expression is fixed both grammatically and lexically.

For example:Put a sock in it = ‘stop talking’

Lexical Relationships

Antonyms Opposites of a word Complementary: Alive/deadpresent/absent fail/pass Gradable pairs: Small/big hot/cold fast/slow happy/sad


Creating antonyms by affixing: Likely/unlikely Able/ unable Smoker/nonsmoker Tolerant/intolerant Exceptions: Add ‘in’ to following words and explain the

meaning: Flammable valuable


Homonyms (homophones) Different meaning but same pronunciation To, too, two Homonyms can create ambiguity: I’ll meet you by the bank.


Hyponymy◦ scarlet, vermilion, carmine, and crimson are all

hyponyms of red (their hypernym), which is, in turn, a hyponym of color.

◦ What are these hyponyms andwhat is their hypernym?


Semantic PropertiesZeroing in on “meaning”

Consider this sentence:The assassin killed Kennedy.

What can you say about what happened? What kind of people were involved?

This kind of information, for example that assassin means a human, a murderer, and a killer of important people, are examples of the semantic features of a word.

Relating words by looking at commonalities. Big vs. Red Semantic property: “about size” Semantic property: “about color” Buy vs. sell Semantic property: “change in possession”

Semantic properties

Quick exercise: Determine a common semantic property

among the following words:

1) Hen aunt widow woman girlmaiden grandmother

2) Doctor dean professorteenager bachelor parent babychild

Semantic properties

Semantic properties One way of representing meaning is with

semantic features. This is a device we use to indicate the presence or absence of semantic properties.

For example, woman would appear as [+female, +human, -young, …] while girl would be [+young] and man would be [-female].

Concept of Semantic features

Man [+MALE], [+ADULT], [+HUMAN] Boy [+MALE], [+YOUNG], [+HUMAN] Bachelor [+MALE], [+UNMARRIED],

[+HUMAN] Woman [+FEMALE], [+ADULT],

[+HUMAN] Girl [+FEMALE], [+YOUNG],

[+HUMAN]

Semantic properties

These properties are overlapping:

MALE

ADULTPARENT

father

bachelor

mother

boy

woman

Semantic Properties and Meaning For the most part no two words have

exactly the same meaning; additional semantic properties make for increasingly finer distinctions.

For example, what semantic property distinguishes between “slap” and “hit”?

Semantic Features and Syntax Incorrect “matching” of the semantic

features of different elements of a sentence can result in ungrammatical (but syntactically sound) sentences:

The man [-female] was pregnant [+female].I sawed [+solid] the water [-solid].

The ideas [-living] are sleeping [+living].

PragmaticsThe importance of context

http://www.thaimarketer.com/images_writer/wiroj/whats-up.gif

is concerned with the interpretation of meaning in context.

2 contexts: Linguistic context (discourse) Situational context (anything non-linguistic)

Pragmatics…

Within discourse, preceding sentence often affect the meaning of following sentences.

Reference/meaning of pronouns often depends on prior discourse.

Prior discourse often disambiguates words like bank.

Linguistic context

Sometimes homonyms and ambiguous structures cause confusion: What do they mean!? AUTOMATIC WASHING MACHINES: PLEASE REMOVE ALL YOUR

CLOTHES WHEN THE LIGHT GOES OUT Outside a secondhand shop: WE EXCHANGE ANYTHING - BICYCLES,

WASHING MACHINES, ETC. WHY NOT BRING YOUR WIFE ALONG AND GET A WONDERFUL BARGAIN?

Outside a disco: SMARTS IS THE MOST EXCLUSIVE DISCO IN TOWN. EVERYONE WELCOME

…is the nonlinguistic environment in which discourse happens and includes speakers, hearers, any others present, their beliefs, physical environment, subject of conversation, time of day etc.

Situational context

The reference of some words entirely rely on situational context of the utterance.

First- and second-person pronouns (I, me, you, yours etc) are always deictic.

Third-person pronouns are deictic if they are free. If they are bound, their reference is known from linguistic context.

Deixis (dike-sis)

Following expressions are deictic:

Time deixis & place deixis

Now then tomorrowthis time that time seven days ago2 years from now Last week Next April

here There This placeThis city This farm Those buildingsOver there These

mountainsThis country
