Word History

Etymology

Noun (1)

Middle English, going back to Old English, "grain of a cereal grass, seed, berry," going back to Germanic *kurno- (whence also Old Frisian, Old Saxon, Old High German & Old Norse korn "grain of a cereal grass, seed," Gothic kaurn), going back to European Indo-European *ǵr̥H-no-, whence also Latin grānum "seed, especially of a cereal grass," Old Irish grán, Welsh grawn, Old Church Slavic zrĭno "grain, seed," Serbian & Croatian zȑno, Russian zernó, Lithuanian žìrnis "pea"

Note: The noun *ǵr̥H-no is sometimes taken to be a zero-grade derivative of Indo-European *ǵerh₂- "become old, ripen" (see geriatric entry 1), but this has been disputed.

Verb

derivative of corn entry 1

Noun (2)

Middle English corne, probably borrowed from Medieval Latin cornū "horn, horny excrescence," going back to Latin, "horn" — more at horn

Note: Late Old English corn in this sense, attested in the medical text Lacnunga, a collection of remedies, charms and prayers, may be from Latin or an extended sense of Old English corn corn entry 1.
