postérieur

postérieur refers to the rear or back part of something. In anatomy, it describes the posterior aspect of the body or a body part. For example, the posterior muscles of the thigh are located at the back of the leg. The term is also used in other contexts, such as describing the posterior side of an object or a position. In geometry, the posterior angle of a triangle is opposite to a given side. It can also denote a sequence of events, where posterior events occur after prior ones. The opposite of postérieur is antérieur, meaning front or before.
