forebode 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.

Old English bodian "proclaim, announce; announce beforehand, foretell," from boda "messenger," probably from Proto-Germanic *budon- (source also of Old Saxon gibod, German gebot, Old Norse boð), from PIE root *bheudh- "be aware, make aware."

With good or ill, "give a (good or bad) portent or promise," late 14c. As a shortened form of forebode "presage" (usually something evil), it dates from 1740. Related: Boded; boding.

late 14c., "a predilection, portent, omen," from fore- + verbal noun from bode. Meaning "sense of something bad about to happen" is from c. 1600. Old English equivalent form forebodung meant "prophecy." Related: Forebodingly.
