Origin & History of “hot”

Hot is the English member of a family of adjectives widespread in Germanic, but with very few outside relatives. Its first cousins are German heiss, Dutch heet, Swedish het, and Danish hed, which point back to a prehistoric Germanic ancestor *khaitaz (the English noun and verb heat come from the same source). Lithuanian kaisti and Latvian kaist ‘become hot’ are allied forms.
