Tittle \Tit"tle\, n. [OE. titel, titil, apparently a dim. of tit, in the sense of small; cf. G. t["u]ttel a tittle, dim. of OHG. tutta teat. Perhaps, however, the same word as title, n.]

A particle; a minute part; a jot; an iota.

It is easier for heaven and earth to pass, than one tittle of the law to fail. --Luke xvi. 17.
