1. SEMANTICS

2. SEMANTICS 1. Study of linguistic meanings
2. Explores the variety of meanings and meaning relationships that hold between words and sentences
3. Has 2 sub-domains: Lexical (words) and sentential (sentences)

3. denotations VS referents
Denotation: literal meaning of word/phrase
Referent: the actual entity (ies) that a word signifies.
Reference: the relationship that exists between a word and its referent(s).

6. denotations VS referents
c) The women who walked on the moon
Group of women who stepped foot on the moon… and walked a few steps
The women who walked on the moon
Yep, but it turns out there hasn’t actually been any woman who has walked on the moon before – So this phrase should have no valid referent. (But it still retains its denotation!)

12. logical entailment
Sentential semantics – Relations between sentences AKA Logical connections
Paraphrase
Entailment
Contradiction
Presupposition
Yep – as a side note, we can define paraphrases as follows:
A is a paraphrase of B if A and B entail each other.

13. Definition of entailment:
logical entailment
Definition of entailment:
Proposition A entails Proposition B if the truth of A makes B necessarily true.
i.e The truth of sentence A ensures the truth of sentence B.
Lecture example
A: I boiled an egg.
B: I cooked an egg.

14. logical entailment “The truth of sentence A makes B necessarily true.”

24. presupposition (B) A. Who killed Sylvia? Sylvia is dead
Murderer is unknown
There must be a Sylvia
Yes, there are many such underlying presuppositions in these questions :)
We could come up with a general presupposition for wh-questions too:
“Who killed Sylvia” -- presupposes --> “Someone killed Sylvia”
“Where did you put the cheese” --> “You put the cheese somewhere”
“Why is there sadness in the world” --> “There is sadness in the world”
In other words, everything except the wh-word is presupposed by the question.

25. presupposition (B) B. Where did you put the cheese?
Cheese has to exist in this world
The cheese is not at its original position
Someone/something is responsible for misplacing the cheese

26. presupposition (B) C. Why is there sadness in the world?
There is must be an emotion called sadness in the world
A world has to be in existence
