Do you know ghouls from goblins and ghosts?
early 15c., "shadow, shade," from Middle French ombrage "shade, shadow," from Latin umbraticum, neuter of umbraticus "of or pertaining to shade," from umbra "shade, shadow," from PIE root *andho- "blind, dark" (cf. Sanskrit andha-, Avestan anda- "blind, dark"). Many figurative uses in 17c.; main remaining one is the meaning "suspicion that one has been slighted," first recorded 1610s; hence phrase to take umbrage at, attested from 1670s.
