Word Origin & History
umbrage1426, "shadow, shade," from M.Fr. ombrage "shade, shadow," from L. umbraticum, neut. of umbraticus "of or pertaining to shade," from umbra "shade, shadow," from PIE base *andho- "blind, dark" (cf. Skt. andha-, Avestan anda- "blind, dark"). Many fig. uses 17c.; main remaining one is the meaning "suspicion
that one has been slighted," first recorded 1620; hence phrase to take umbrage at, attested from 1680.
