Truth conditions
- if you know a sentence's meaning, then you know the conditions under which it would be true.
- If conditions hold- the sentence is synthetically true
- Declarative utterances have straightfoward truth conditions. Interrogative and imperative utteraces don't have truth values in the same sense
-
Entailments
things entailed by the sentence- straightforward inferences. If two sentences entail each other, they are synonymous, or paraphrases of each other.
-
Presuppositions
inferences that are assumed to be true, rather than directly asserted
