An Etymological Dictionary of the German Language/gram

by Friedrich Kluge

gram, adj., ‘adverse, hostile, vexed, angry,’ from MidHG. and OHG. gram, ‘angry, peevish, irritated, enraged’; corresponding to the equiv. OSax. gram, Du. gram, AS. gram, OIc. gramr. To Goth. *grama- (from pre-Teut. ghromo-), Gr. χρόμαδος, ‘gnashing’ (and χρεμέθω, Lat. fremo, ‘I gnash’?), seem allied. From the Teut. adj. is derived the Romance cognate, Ital. gramo, ‘gloomy.’ — Gram, m., as a subst. even in MidHG. gram. From the same root. grimm is derived. See the latter word.
