drill

v.

c.1600 (implied in drilling), from Dutch drillen "to bore (a hole), turn around, whirl," from Proto-Germanic *threljanan (cf. Middle High German drillen "to turn, round off, bore," Old Engish þyrel "hole"), from PIE *tere- "to turn, rub" (see throw (v.)). Sense of "to instruct in military exercise" is 1620s (also in Dutch drillen and in the Danish and German cognates), probably from the notion of troops "turning" in maneuvers. Extended noun sense of "the agreed-upon procedure" is from 1940. Related: Drilled.
