From Jargon File (4.3.1, 29 Jun 2001) [jargon]:

cons /konz/ or /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.
