early 15c., "a special quality or thing;" mid-15c. as "quality of being special," from Old French specialte, especialte "nature, special quality, particularity; special point, distinction," and directly from Latin specialitatem (nominative specialitas) "peculiarity, particularity" from specialis "individual, particular" (see special, adj.). French form spécialité (especially in reference to restaurant dishes) is recorded in English from 1839.
