O.E. forca "forked instrument used by torturers," a Germanic borrowing (cf. O.N. forkr) from L. furca "pitchfork; fork used in cooking," of uncertain origin. Table forks were not generally used in England until 15c. The word is first attested in this sense in English in a will of 1463, probably from O.N.Fr. forque (O.Fr. furche, Mod.Fr. fourche), from the Latin word. Of rivers, from 1753; of roads, from 1839. The verb "to divide in branches, go separate ways" (early 14c.) is from the noun. Related: Forked; forking. The slang verb phrase fork up (or out) "give over" is from 1831.
