programming language
<language> A formal language in which computer programs are written. The 
definition of a particular language consists of both syntax (how the various 
symbols of the language may be combined) and semantics (the meaning of the 
language constructs).
 
Languages are classified as low level if they are close to machine code and high 
level if each language statement corresponds to many machine code instructions 
(though this could also apply to a low level language with extensive use of 
macros, in which case it would be debatable whether it still counted as low 
level). A roughly parallel classification is the description as first generation 
language through to fifth generation language.
 
The other major classification of languages distinguishes between imperative 
languages, procedural language and declarative languages.
