The word can describe actions or a person's behavior. An example from the St. Paul Pioneer Press describes a Bob Dylan concert as churlish but also self-assured. This is because Dylan's focus is on his message, not necessarily what the audience wants. Historically, the word has evolved significantly. In Old English, "ceorl" referred to a free peasant with certain rights. Over centuries, particularly after the Norman Conquest, the meaning shifted. The term "ceorl" diminished in status, eventually meaning a lowly peasant. Similarly, "churlish" originated from "ceorlisc," a descriptor of rank. Today, it signifies a boorish or insensitive individual.
