bewilder (v.) Look up bewilder at Dictionary.com
1680s, "confuse as to direction or situation," also, figuratively, "perplex, puzzle, confuse," from be- "thoroughly" + archaic wilder "lead astray, lure into the wilds," which is probably a back-formation from wilderness. An earlier word with the same sense was bewhape (early 14c.) and there is a 17c. use of bewhatle.
