词源
From Middle English periode, from Middle French periode, from Medieval Latin periodus, from Ancient Greek περίοδος (períodos, “circuit, orbit, a recurring interval of time, path around”), from περι- (peri-, “around”) + ὁδός (hodós, “way”). Displaced native Middle English tide (“interval, period, season”), from Old English tīd (“time, period, season”), as well as Middle English elde (“age, period”), from Old English ieldu (“age, period of time”).
