The Jargon File (version 4.4.7, 29 Dec 2003):

cons
 /konz/, /kons/

    [from LISP]

    1. vt. To add a new element to a specified list, esp. at the top. “OK, cons
    picking a replacement for the console TTY onto the agenda.”

    2. cons up: vt. To synthesize from smaller pieces: “to cons up an example”.

    In LISP itself, cons is the most fundamental operation for building
    structures. It takes any two objects and returns a dot-pair or two-branched
    tree with one object hanging from each branch. Because the result of a cons
    is an object, it can be used to build binary trees of any shape and
    complexity. Hackers think of it as a sort of universal constructor, and
    that is where the jargon meanings spring from.
