English has two words spelled corn: grain, inherited from Old English, and the hard patch of skin on the foot, from Latin cornu, horn.[1][2][3]

Pronunciation

  • IPA: /ˈkɔːn/ (UK); /ˈkoɹn/ (US)[4]

corn1 grain

Etymology

It is inherited from Old English corn (“a seed of grain; grain”),[1][2][5] from Proto-Germanic *kurną (“small seed”),[2][3] source also of Old Frisian and Old Saxon korn, Dutch koren, German Korn, Old Norse korn and Gothic 𐌺𐌰𐌿𐍂𐌽 (kaurn),[2][1] from PIE *ǵr̥h₂nóm, from Proto-Indo-European *ǵerh₂- (“to grow old, ripen”), also the source of Latin granum (“grain”) (see grain).[3][5][2]

Earliest recorded meaning

The seed of plants other than cereals, as of a grape or pepper: before 700 in the OED;[6] a seed of grain from about 1000.[6] Barnhart has berecorn, a grain of barley, about 700.[1]

Semantic evolution

A small hard particle, as of sand or salt, is from about 888;[6] Word Origins notes it could even be used of hail.[7] The Old English word meant grain with the seed still in rather than a particular plant, and it came to mean the leading crop of a district:[2] wheat in England, oats in Scotland and Ireland,[2] and in America, from about 1600, maize, at first Indian corn.[2] The verb, to form into grains, is from the 1550s, and to preserve with grains of salt from the 1560s, hence corned beef.[2] Corny, trite, developed in the 1930s from a word for music of a rural kind.[7]

Etymology

It is Middle English corne, borrowed from Old French corn (“horn; a corn on the foot”) (Anglo-Norman corn),[1][2][8] from Latin cornu (“horn”) (see horn),[1][5] from PIE Proto-Indo-European *ḱer- (“horn; head”).[2]
