LispThe family of functional programming languages inspired by John McCarthy's original notation for computations, later becoming Lisp 1.5, MacLisp, InterLisp, and some of the more modern implementations.
The key feature of the Lisp family is that they all are late-bound languages that use parentheses as the basic delimiter of evaluation forms, and all forms are expressions without exception. The uniform syntax turned out to allow the use of metaprogramming through manipulation (via macros) of the list-representation of this syntax, called symbolics expressions, or S-Expressions for short (even shorter, "SEXP").
Lisp is also defined as a program in itself:
(loop (print (eval (read)))), called the read-eval-print loop. Many great books in computer science have been written using or covering this language.
LISP stands for LISt Processing
