Chevron
late Middle English (in heraldic use): from Old French, based on Latin caper ‘goat’; compare with Latin capreoli (diminutive of caper ) used to mean ‘pair of rafters’.
wiktionary
Borrowed from French chevron(“rafter, chevron”), the mark so called because it looks like rafters of a shallow roof, from Vulgar Latin *capriō, from Latin caper(“goat”), the likely connection between goats and rafters being the animal's angular hind legs.
etymonline
chevron (n.)
late 14c., in heraldry, "a device in the shape of an inverted V," from Old French chevron "rafter; chevron" (13c.), so called because it looks like rafters of a shallow roof, from Vulgar Latin *caprione, from Latin caper "goat" (see cab); the hypothetical connection between goats and rafters being the animal's angular hind legs. Compare gambrel, also Latin capreolus "props, stays, short pieces of timber for support," literally "wild goat, chamoix."
