词汇	clicker
词源	clicker n. "one who or that which 'clicks,' in any sense," agent noun from click (v.). Earliest attested sense is slang, "person employed by a shopkeeper to stand at the door and solicit customers" (1680s). It is still thus in Johnson (1755): "clicker. A low word for the servant of a salesman, who stands at the door to invite customers." By 1996 as "a remote control device to operate something (generally a television set) by the 'click' of a button." Entries linking to clicker click v. 1580s, "cause to make a weak, sharp, sound" (transitive), of imitative origin (compare Dutch and East Frisian klikken "to click;" Old French clique "tick of a clock"). Intransitive sense "make a weak, sharp sound" is from 1610s. The figurative sense, in reference usually to persons, "hit it off at once, become friendly upon meeting" is from 1915, perhaps based on the sound of a key in a lock. Mental figurative meaning "to fall into context" is by 1939. Related: Clicked; clicking. updated on December 22, 2017
