Which sentences are correct?

In the incorrect sentences, are the problems

– syntactic? morphological? semantic?

2

Semantic features

The main problem: only animals can eat!

Describe word meaning with features / characteristics

Boy

[+human]

[+male]

[-adult]

Big Mac ?

From last semester, how did we define banana ?

Elephant?

Language?

Please choose three English or Chinese words

Describe them using semantic features with [+…] and [-…]

3

Semantic features

Now look at 101 and ex 1

It seems that we would need a large number of features to describe every word

For pregnant , how many features would we need?

– [+human], [+female], [+big], [+uncomfortable],

[+carrying_baby] (or [+pregnant]?!)

What about hot ? [–cold]?

– Cold ? [–hot]? (The circularity problem)

4

Semantic roles (NOT “RULES”!)

(agent, theme etc)

Semantic features describe word meaning

Semantic roles describe the role words play in a sentence

– Check Yule 102ff

What are the semantic roles of NPs in this sentence?

– John looked at the stars with a telescope

– How about John saw a bright star ex 2

5

Lexical relations

Semantic roles and semantic features explain and define one word

Linguists are also interested in the relationships between words

Two words may have

 the same meaning ( perhaps vs maybe ) opposite meanings ( black vs white ) a broader meaning ( dog vs animal ) a whole-part meaning ( face vs nose )

Give examples of each

6

Lexical relations: Synonyms

Usually not exactly the same meaning

 huge : large,

– baby and infant student and pupil

Or the meaning may be pretty similar, with the difference in the way we use the words

– sick and ill quickly and speedily

知道:曉得:懂:理解 appear : emerge

Task : Can you think of any absolute synonym pairs?

– Are they easier to find in English or Chinese, do you think?

– Is there a reason why absolute synonyms should not exist (or should be very rare)?

7

“ Synonymy” across languages: cross- linguistic semantic equivalence

Although cat = 貓

– we know that there is no automatic one-to-one mapping between

English & Chinese (or any other pair) at least, I hope we all know this

Consider again 知道 and 曉得 . And 認識

– Many Romance languages distinguish between 知道 and 認識

In French, aimer can mean either like or love!

The t/v distinction: 你 vs 您

Please comment on other languages you know, regarding these points

8

Antonyms (using * for semantic oddness here)

Non-gradable

If you don’t pass, you fail

If you’re not dead, you’re alive

– But a table is not alive and not dead: can you explain this

?He looks very dead

*She is deader / more dead than him

Gradable

*If you’re not rich, you’re poor

He looks very rich.

She is richer than him.

Prototypes

If you close your eyes and think of this:

– BIRD

You will probably see a robin, or a sparrow

Not a chicken, and not an ostrich, and not a humming bird.

Could it be different, with you Chinese speakers, for ostrich ?

Write prototypes and non-prototypes for 2 categories

11

Some homonyms are just homophones
