Origin & History of “high”

High is an ancient word. It goes right back to Indo-European *koukos, which is related to a number of terms denoting roughly ‘rounded protuberance’: Sanskrit kucas ‘breast’, for instance, Russian húcha ‘heap’, and Lithuanian kaukas ‘swelling, boil’. Evidently the notion of ‘tallness’, central to modern English high, is historically a secondary development from the notion of being ‘heaped up’ or ‘arched up’. The Germanic descendant of *koukos was *khaukhaz, which produced German hoch, Dutch hoog, Swedish hög, Danish hoj, and English high. Height is a derivative of *khaukh-.
