foreshorten v.

Middle English for-, fore-, from Old English fore-, often for- or foran-, from fore (adv. & prep.), which was used as a prefix in Old English as in other Germanic languages with a sense of "before in time, rank, position," etc., or designating the front part or earliest time.

mid-14c., shortenen, "make shorter;" late 14c., "grow shorter," from short (adj.) + -en (1); the earlier form of the verb was simply short, from Old English sceortian "to grow short, become short; run short, fail," gescyrtan "to make short." For cookery sense (1733) see shortening. Related: Shortened.
