From Middle English houre, hour, oure, from Old French houre, from Latin hōra (“hour”), from Ancient Greek ὥρα (hṓra, “any time or period, whether of the year, month, or day”), from Proto-Indo-European *yóh₁r̥ (“year, season”). Akin to Old English ġēar (“year”). Doublet of hora and year. Compare horary. Partly displaced native Old English tīd (“time, hour”), whence Modern English tide.
