Protuberance is a noun that refers to a prominent or protruding part or mass that extends outward from a surface. It typically describes a physical feature that stands out or bulges, creating a noticeable difference from the surrounding area. This term can be used to describe various objects or anatomical features that exhibit a significant swelling, prominence, or projection beyond their normal or expected shape.
In a more biological sense, protuberance can denote a lump, bump, or knob that is present on the body of an animal or plant. For instance, it may refer to a protuberance on the head of a deer, serving as a distinctive feature or weapon during territorial disputes or mating rituals. Similarly, in botany, a protuberance could describe a swollen or enlarged region of a plant, such as a bud, nodule, or tuber.
Beyond the physical realm, protuberance can also be used metaphorically to describe elements that prominently stand out in a conceptual or abstract sense. For instance, one might speak of a person's arrogance as a protuberance in their personality, emphasizing its noticeable and protruding nature. In this context, protuberance indicates a characteristic or attribute that is highly visible or conspicuous, often drawing attention or having a considerable impact on a situation or perception.

The word protuberance has Latin roots. It is derived from the Latin word protuberantia, which is made up of two components: pro, meaning forth or forward, and tuber, meaning knob or swelling. Therefore, protuberance essentially means a swelling that projects forward.
