mid-15c., mokken, "make fun of," also "to trick, delude, make a fool of; treat with scorn, treat derisively or contemptuously;" from Old French mocquer "deride, jeer," a word of unknown origin. Perhaps from Vulgar Latin *muccare "to blow the nose" (as a derisive gesture), from Latin mucus; or possibly from Middle Dutch mocken "to mumble" or Middle Low German mucken "grumble." Perhaps ultimately it is imitative of such speech. Related: Mocked; mocking. Replaced Old English bysmerian. The sense of "imitate, simulate, resemble closely" (1590s, as in mockingbird ; also see mock (adj.)) is from the notion of derisive imitation.
prefixed to a noun, "feigned, counterfeit, spurious; having a close (but deceptive) resemblance," 1540s, from mock, verb and noun.

From mid-15c. as "joking, making mischievous pleasantries." Mockage also was common 16c.-17c.
also mocking-bird, passerine bird of the southerly parts of the U.S., noted for the song of the males and its skill in imitation, 1670s (mock-bird is from 1640s), from present-participle adjective of mock (v.) + bird (n.1).
