  In formal semantics and philosophy of language, a meaning postulate is a way of stipulating a relationship between the meanings of two or more words. They were introduced by Rudolf Carnap as a way of approaching the analytic/synthetic distinction. Subsequently, Richard Montague made heavy use of meaning postulates in the development of Montague grammar, and they have features prominently in formal semantics following in Montague's footsteps.

  3. "X is not awake, therefore X is asleep." In meaning postulate this would look like this:
