n.1parasitic blood-sucking arachnid animal, Old English ticia, from West Germanic *tik- (cf. Middle Dutch teke, Dutch teek, Old High German zecho, German Zecke “tick”), of unknown origin. French tique (mid-15c.), Italian zecca are Germanic loan-words. n.2mid-15c., “light touch or tap,” probably from tick (v.) and cognate with Dutch tik, Middle High German zic, and perhaps echoic. Meaning “sound made by a clock” is probably first recorded 1540s; tick-tock is recorded from 1848. n.3“credit,” 1640s, shortening of ticket (n.). v.early 13c., “to touch or pat,” perhaps from an Old English verb corresponding to tick (n.2), and perhaps ultimately echoic. Cf. Old High German zeckon “to pluck,” Dutch tikken “to pat,” Norwegian tikke “touch lightly.” Related: Ticked; ticking. To tick (someone) off is from 1915, originally “to reprimand, scold.” The verbal phrase tick off was in use in several senses at the time: as what a telegraph instrument does when it types out a message (1873), as what a clock does in marking the passage of time (1846), to enumerate on one’s fingers (1899), and in accountancy, etc., “make a mark beside an item on a sheet with a pencil, etc.,” often indicating a sale (by 1881). This might be the direct source of the phrase, perhaps via World War I military bureaucratic sense of being marked off from a list as “dismissed” or “ineligible.” Meaning “to annoy” is recorded from 1975. n.
