Acerb

Acerb is an adjective derived from the Latin word "acerbus," which means sharp or bitter. In English, acerb is used to describe something that is harsh, bitter, or caustic in tone or flavor. It can also refer to a sharp or pointed object, such as an acerb edge or acerb tip. The term is often used in a critical or sarcastic context, as in "acerb remarks" or "acerb wit." For example, a critic might describe a film as having an acerb tone, meaning it is harshly critical of its subject matter. In a culinary context, acerb might describe a sauce or condiment that has a strong, bitter flavor. The term can also be used metaphorically to describe a person's sharp or biting personality.
