Old English gear (West Saxon), ger (Anglian) "year," from Proto-Germanic *jēr "year" (source also of Old Saxon, Old High German jar, Old Norse ar, Danish aar, Old Frisian ger, Dutch jaar, German Jahr, Gothic jer "year"), from PIE *yer-o-, from root *yer- "year, season" (source also of Avestan yare (nominative singular) "year;" Greek hōra "year, season, any part of a year," also "any part of a day, hour;" Old Church Slavonic jaru, Bohemian jaro "spring;" Latin hornus "of this year;" Old Persian dušiyaram "famine," literally "bad year"). Probably originally "that which makes [a complete cycle]," and from verbal root *ei- meaning "to do, make."
