Middle English ere, from Old English ēare; akin to Old High German ōra ear, Latin auris, Greek ous
Noun (2)
Middle English er, ere, going back to Old English ēar (Northumbrian æhher), going back to Germanic *ahaz (whence also Old Frisian ār "ear of grain," Middle Dutch aer, aere, Old Saxon ehir, Old High German ah, ahar, ehir, Old Norse ax, Gothic ahs), going back to Indo-European *h2eḱ-es-, s-stem derivative from the base *h2eḱ- "sharp, pointed" (in reference to a spike of grain perhaps originally referring to the awns, then generalized to the entire spike), whence also Latin acer-, acus "husks of grain or legumes, chaff," Tocharian B āke "end," Tocharian A āk — more at edge entry 1
Note: The diverse outcomes in Germanic assume generalization throughout the paradigm of the original stem variants: most forms from oblique stems *ahuz-, ahiz-, but Old High German ah, from nominative *ahaz and Old Norse ax, Gothic ahs, from a syncopated stem *ah-sa-.
