Cons

/konz/ or /kons/ [LISP, "construct"] A Lisp function which takes an element H and a list T and returns a new list whose head is H and whose tail is T.

In Lisp, "cons" is the most fundamental operation for building structures.

It actually takes any two objects and returns a "dotted-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.
