recursion
noun
- Mathematics a.

The Fibonacci sequence is defined by recursion.b. A set of objects so defined.c. A rule describing the relation between an object in a recursive sequence in terms of the preceding objects.
- Linguistics The property of languages in which a structure, such as a phrase or clause, may form a part of a larger structure of the same kind, allowing for a potentially infinite variety of constructions.

Late Latin recursiō, recursiōn-, a running back, from Latin recursus, past participle of recurrere, to run back; see recur.recursion
Noun
(plural recursions)
- The act of recurring.
- (mathematics) The act of defining an object (usually a function) in terms of that object itself.
- n! = n Ã— (n âˆ’ 1)! (for n > 0) or 1 (for n = 0) defines the factorial function using recursion.
- (computing) The calling of a function from within that same function.
- This function uses recursion to compute factorials.
Origin
From Latin recursiÅ (“the act of running back or again, return"), from recurrÅ (“run back; return"), from re- (“back, again") + currÅ (“run").
recursion - Computer Definition
In programming, the ability of a subroutine or program module to call itself. It is helpful for writing routines that solve problems by repeatedly processing the output of the same process. See recurse subdirectories.
