semantics
<theory >
The meaning of a string in some language, as opposed to syntax which describes how symbols may be combined independent of their meaning. The semantics of a programming language is a function from programs to answers. A program is a closed term and, in practical languages, an answer is a member of the syntactic category of values. The two main kinds are denotational semantics and operational semantics.
