Etymology

Origin of tick¹

First recorded in 1400–50; late Middle English tek “little touch”; akin to Dutch tik “a touch, pat,” Norwegian tikka “to touch or shove slightly”; see tickle

Origin of tick²

First recorded before 900; Middle English teke, tyke, Old English ticia, perhaps spelling error for tiica (i.e. tīca ) or ticca; akin to Low German tieke, German Zecke

Origin of tick³

First recorded in 1425–75; late Middle English tikke, teke, tyke (cognate with Dutch tijk, German Zieche ), ultimately derived from Latin tēca, thēca, from Greek thḗkē “case”

Origin of tick⁴

First recorded in 1635–45; short for ticket

Explanation

To tick is to make a steady tapping sound. When something ticks — be it a clock, a watch, an oven timer, or a metronome — it’s usually a reminder that time is passing. The verb tick originally meant "to touch or pat." The current meaning may be related to the sound of a hand patting or tapping a surface. Another kind of tick is a small blood-sucking parasite. This nastier tick has a different root, the Old English ticia.
