2.2 [as modifier] Linguistics Denoting a basic unmarked linguistic string. OriginOld English cyrnel, diminutive of corn1. corn from Old English: Corn, meaning ‘the seed of wheat and similar plants’, is an Old English word whose root may date back as far as farming itself. The modern sense of corny is a development of an earlier sense, dating from the 1930s, that described something, especially music, of a simple and unsophisticated type that appealed to people living in the country. Kernel (Old English) is based on corn and was originally a ‘little corn or seed’. The other kind of corn (Late Middle English), the small area of thickened horn-like skin on your foot, comes from Latin cornu ‘horn’. Cornu, which could also mean ‘tip’ or ‘corner’, is the source too of corner (Middle English)—you can think of a corner as the part of something that sticks out or forms the tip. The trumpet-like cornet (Late Middle English) is now made from brass, but it was originally a wind instrument made out of a horn, and Latin cornu is again the source. The early 20th century ice-cream cornet gets its name because it resembles that of the instrument. One brand of ice cream is called a Cornetto (‘little horn’), and this Italian word was also the name of an old musical instrument, a straight or curved wooden wind instrument with finger holes and a cup-shaped mouthpiece.
