What does the root word "later" mean?

The root word "later" originates from the Latin term "lateral," which refers to something that is situated at or extending to the side. This definition emphasizes spatial relationships, particularly those that involve positioning away from the central or midline of an object or organism. Understanding this root is crucial in esthetics, as many procedures, treatments, and anatomy descriptions may refer to lateral movements or sections, especially when discussing techniques that target specific areas on the side of the face or body. For instance, knowledge of lateral structures is essential for administering injections or conducting facial assessments effectively.
