choleric

Imagine someone who flares up at the slightest provocation—that's often described as choleric. It doesn't just mean angry; it suggests a deeply ingrained tendency toward irritability and a quick temper. Historically, this term came from ancient medical beliefs linking yellow bile (cholé in Greek) to an excitable temperament. You might describe a fiery historical figure like a choleric general, always ready for battle, or a choleric old man yelling at kids to get off his lawn. It's stronger than simply being "in a bad mood"; it's about being prone to anger.

The word "choleric" describes someone who is easily provoked to anger, quick-tempered, and often irascible. It goes beyond momentary frustration—a choleric person has a disposition toward wrathfulness. The origin of the word lies in ancient Greek medicine, where it was believed that an excess of yellow bile (the humor cholé) caused such a temperament.

While we no longer believe in humors, the term persists to describe someone with a volatile and often aggressive personality. You might encounter "choleric" when reading historical accounts—think of a choleric king known for his unpredictable outbursts or a choleric reformer fiercely advocating for change. It's not simply about feeling angry; it's about having an inherent, almost defining characteristic of being easily angered.

The term can also describe speech, actions, or reactions characterized by that heat: "His choleric response to the news surprised everyone." In older or more technical writing, you may also see it used in its original, humoral sense to mean “relating to bile” or “bilious,” but in modern English it’s most often applied to people who exhibit a consistently irritable, easily angered disposition.
