gloaming (n.) Look up gloaming at Dictionary.com
Old English glomung "twilight," formed (probably on model of æfning "evening") from glom "twilight," related to glowan "to glow" (hence "glow of sunrise or sunset"), from Proto-Germanic *glo- (see glow (v.)). Fell from currency except in Yorkshire dialect, but preserved in Scotland and reintroduced by Burns and other Scottish writers after 1785.
