early 15c., from Middle French timoureus (14c.), from Medieval Latin timorosus "fearful," from Latin timor "fear, dread, apprehension, anxiety; religious awe, reverence," from timere "to fear, be afraid, dread," of unknown origin. Some early senses in English seem to show confusion with Middle English temerous "rash" (see temerity). Related: Timorously; timorousness.
