Etymology: Forswart is an old English adjective meaning blackened by soot, and its story is almost entirely in its prefix. The "for-" here is not the familiar "for" of "forget" or "forbid" but an intensifier that gives the sense of thoroughness, so the word describes something blackened all the way through rather than lightly dusted. The base is "swart," meaning black or dark, a word that survives in English today mostly in poetry and in the related "swarthy." The word came into English in Middle English, and it was built on the verb "forswarten," meaning to make thoroughly black. Its form therefore reflects a process in which an ordinary adjective was turned into a verb and then back into a descriptive adjective, with the intensifying prefix doing the heavy work.
