Etymology: Subcompartment is a plain formation: the prefix "sub-", meaning "under" or "below" in Latin, attached to "compartment". It describes a smaller section within a space that is already divided into sections, so the parts stack like nested boxes. The base word has a longer and more interesting path. It descends from the Latin "compartiri", meaning "to divide into parts", built from "com-" (together, with) and "partiri" (to share out), which itself comes from "pars", "part". From Italian "compartimento", a design term for a division within a pattern, French borrowed the word as "compartiment", and English took it in the form "compartment". The sense moved from dividing a whole into shares to a bounded section of a larger object, such as a railway carriage, a drawer or a cell in a box. Because "subcompartment" is a modern English compound made from these two parts, the word itself is a straightforward combination rather than an old borrowing, and its meaning follows directly from the two elements.
