Capricious: impulsive; fickle; whimsical; changeable; erratic
The ancient gods were capricious. They were happy one moment, and irate the next.
Source: Capricious came to English via the French word capricieux meaning capricious, or whimsical. In French, a whim is caprice. Beyond that, etymologists aren’t sure. Some guess it could have come from capra, the Latin word for goat. Possibly a reference to the frisky nature of goats.
Synonyms: erratic, unpredictable, arbitrary, unstable
