# notes on semantics
Semantics is the study of **meaning**.
How do we know what sentences are true and which are false?
What does it *mean* for a sentence to be true?
What conditions must hold for a sentence to be true?
Formal semantics attempts to answer those questions by providing a *framework* for determining what *conditions* must hold for a sentence to be true.
This framework is [first-order/predicate logic](../mathematics/logic) and the [simply-typed lambda calculus](../plt/lambda-calculus). On top of this, we often build set theory, relying on *characteristic functions* of the lambda calculus to denote *set membership*.
