Simplified etymology
Morose, recorded in English from the mid-16th century, ultimately traces back to Latin mos “custom,” whose plural mores means “morals”; the same Latin source lies behind moral.
Etymology
From French morose, from Latin mōrōsus (“particular, scrupulous, fastidious, self-willed, wayward, capricious, fretful, peevish”), from mōs (“way, custom, habit, self-will”). See moral.
