semantics
     
         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}.
