chevron

First appearing in English in the 14th century, chevron derives via Middle English and Anglo-French from the Vulgar Latin word caprio, meaning "rafter (probably due to its resemblance to two adjoining roof beams)." It is also related to the Latin noun caper, meaning "goat," again likely based on the resemblance of a V-shape to a goat’s horns. "Caper" is also an ancestor of "Capricorn," the tenth sign of the zodiac, represented by a goat. The resemblance of "chevron" to "chèvre," the French word for "goat" and our word for a kind of cheese that comes from goat’s milk, is no coincidence, as that word derives from "caper" as well.
