Capricious

The word “capricious” refers to someone or something that is unpredictable, impulsive, or subject to sudden changes in mood or behavior. It describes a tendency to act on whims or without apparent reason.

Interesting fact: The word “capricious” comes from the Italian word “capriccio,” which means a sudden change of mind or a whim. It is derived from the Latin word “capra,” meaning goat. This connection to goats may stem from the idea that goats are known for their unpredictable and impulsive behavior.
