sentence functor

Quick Reference

In logic, a string of words and sentence variables (usually represented by Greek letters) such that if the sentence variables are replaced by declarative sentences, then the whole becomes a declarative sentence with the inserted sentences as constituents. A typical example is: Many people have said that φ, but it is a lie that ψ. Replacing the sentence variables, this might become Many people have said that fruit is nourishing, but it is a lie that Hitler loved animals. See also truth functor, truth table. [From Latin functio a function, from fungi to perform]
