thumb|Tree (data structure)|Tree data structure representing the S-expression (* 2 (+ 3 4))
In computer programming, an S-expression (or symbolic expression, abbreviated as sexpr or sexp) is an expression in a like-named notation for nested list (tree-structured) data. S-expressions were invented for, and popularized by, the programming language Lisp, which uses them for source code as well as data.
