semantics definition

The scientific or philosophical study of the relations of words and their meanings.

Note: Semantics is commonly used to refer to a trivial point or distinction that revolves around mere words rather than significant issues: “To argue whether the medication killed the patient or contributed to her death is to argue over 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.
