Origin and history of specification

specification(n.)

1610s, "act of investing with some quality," from Medieval Latin specificationem (nominative specificatio), noun of action from past-participle stem of Late Latin specificare "mention particularly," from Latin specificus (see specific).

The meaning "technical particular, article, or item that has been described in detail" is attested from 1833, originally in patent law, where it refers to the applicant's description of the construction and use of the device; short form spec for this is attested by 1956.

1630s, "having a special quality," from French spécifique and directly from Late Latin specificus "constituting a kind or sort" (in Medieval Latin "specific, particular"), from Latin species "kind, sort" (see species) + -ficus "making, doing," from combining form of facere "to make."

The earlier form was specifical (early 15c., specificalle, "narrow, specific"). The meaning "precise, regarding a definite subject, in accord with what is determined" is recorded by 1740. Related: Specifically; specificness; specificalness.
