compartment
UK: kəmˈpɑːtmənt | US: kəmˈpɑːrtmənt
n. a separate section or space within a larger structure (e.g., a train compartment)
n. a distinct part or category of something (e.g., compartment of knowledge)
The word "compartment" originates from Latin compartiri ("to divide into parts"), combining com- (intensifying "together") and part- (from pars, meaning "section"). The suffix -ment was added in Middle French to form a noun indicating the result of an action. Over time, it evolved to mean a subdivided space or conceptual category, reflecting its root idea of "divided sections united within a whole."
