The word "protuberance" refers to a part of something that sticks out or bulges outward. It can be used to describe any kind of physical feature that protrudes from an object or living thing, such as a bump on a surface or a bump on a person's body. For example, a protuberance on a tree might be a large knot in the wood, while a protuberance on a person's body might be a mole or a fatty lump. The word is generally used in more formal or technical contexts, such as in scientific or medical descriptions.
