Explanation

Hysterical means "marked by uncontrollable, extreme emotion." If your favorite sports team wins a championship, you might get hysterical and start weeping and screaming all at once. Hysterical comes from the medical Latin word hystericus, which described a female neurotic condition, thought to be caused by a dysfunction of the uterus.
