Context dependence

In semantics, context dependence is the phenomenon that the interpretation of an expression depends on the context in which it is used.

Comment

Deictic pronouns are a clear case of context dependent expressions, but other expressions can also be context dependent, such as many or big, because what counts as many or big always depends on the context in which these words are used (a big mouse may be a small animal).
