LISP (LISt Processing) is a programming language dating back to 1958; only FORTRAN is older among programming languages still in use.
It's known as "the programming language with all the parentheses" due to its syntax consisting of deeply nested structures. (This attribute is shared by TRAC programming language, but LISP is better-known.) LISP treats everything as a list which can be manipulated by its operators, including LISP commands themselves, so programs are able to be self-modifying.
Some of its cryptically-named operators, such as car (for the first element of a list) and cdr (for the remainder of the list), derive from the particulars of the register structure of the original computer it was implemented on (where these operators stand for "contents of address register" and "contents of decrement register").
