What does compartmental mean?
Compartmental is an adjective describing something divided into distinct sections or compartments, whether physically or figuratively. In its literal sense it applies to structures, containers, or organisms organized into separate parts, as in a compartmental storage box or the compartmental layout of a ship's hull. More commonly encountered today is its figurative use, describing a mind, life, or system whose different areas are kept deliberately isolated from one another — a person may lead a compartmental existence in which career, family, and private beliefs never intersect. The word derives from "compartment," tracing back through French to the Latin "pars," meaning "part." It appears most often in formal registers: architecture, engineering, psychology, and security contexts all rely on it. Its figurative sense can carry a subtle note of disapproval, suggesting emotional distance, rigidity, or concealment, which makes it a useful word for characterizing both physical design and human behavior with precision.

Etymology of compartmental
Compartmental comes from "compartment," a word borrowed from French in the early modern period, ultimately built on Latin "com-" (together) and "pars" or "part-" (part). The suffix "-al" turns the noun into an adjective meaning "of or relating to compartments." It shares this Latin root "part-" with a broad family of English words, including partial, partition, participate, and particle.
