From northern Europe, the word traveled south again to become a cognate of the Latin cornu, the basis for the English word for grains (and the specific version seen in Iowa), for several scientific words (e.g., cornicle,
cornify, etc.), for the unicorn as a mythical beast, for the region of Capricorn in the zodiac, for the cornucopia, an object Americans associated with the Thanksgiving celebration, and for the musical bugle, akin to the cornet.
Although squamous cells are thought to be precancerous, they are initially a response to injury: They "
cornify," or interlock, to form a tough extra barrier against toxic exposures.
