Lisp (historically LISP, an abbreviation of "list processing") is a family of programming languages with a long history and a distinctive, fully parenthesized prefix notation.[3] Originally specified in the late 1950s, it is the second-oldest high-level programming language still in common use, after Fortran.[4][5] Lisp has changed since its early days, and many dialects have existed over its history. Today, the best-known general-purpose Lisp dialects are Common Lisp, Scheme, Racket, and Clojure.[6][7][8]

Lisp was originally created as a practical mathematical notation for computer programs, influenced by (though not originally derived from)[9] the notation of Alonzo Church's lambda calculus. It quickly became a favored programming language for artificial intelligence (AI) research.[10] As one of the earliest programming languages, Lisp pioneered many ideas in computer science, including tree data structures, automatic storage management, dynamic typing, conditionals, higher-order functions, recursion, the self-hosting compiler,[11] and the read–eval–print loop.[12]

The name LISP derives from "LISt Processor".[13] Linked lists are one of Lisp's major data structures, and Lisp source code is made of lists. Thus, Lisp programs can manipulate source code as a data structure, giving rise to the macro systems that allow programmers to create new syntax or new domain-specific languages embedded in Lisp.

The interchangeability of code and data gives Lisp its instantly recognizable syntax. All program code is written as s-expressions, or parenthesized lists. A function call or syntactic form is written as a list with the function or operator's name first, and the arguments following; for instance, a function f that takes three arguments would be called as (f arg1 arg2 arg3).
