Etymology

The word "bilateral" originates from Latin bilaterālis, combining "bi-" (two) and "lateralis" (pertaining to the side). The root "later" (side) appears in other English words like "lateral" and "unilateral." The term evolved to describe agreements, anatomy, or structures involving two sides, emphasizing symmetry or mutual involvement.
