Origin & History of “tick”
English now has no fewer than four distinct words tick in general use. The oldest, tick ‘mite’ (OE), comes from a prehistoric west Germanic *tik-, which may be related to Armenian tiz ‘bug’. Tick ‘sound of a clock, mark of correctness, etc’ (13th c.) originally meant broadly ‘light touch, tap’; its modern uses are secondary and comparatively recent developments (‘sound of a clock’ appears to have evolved in the 16th century, and ‘mark of correctness’ did not emerge until the 19th century). Tickle (14th c.) is probably a derivative. Tick ‘mattress case’ (15th c.) was borrowed from middle Dutch tēke, which went back via Latin thēca to Greek thḗkē ‘cover, case’. And tick ‘credit’ (17th c.) (as in on tick) is short for ticket.
