Etymology

apartment = apart<separate> + ment<noun suffix>

  • apart: From Old French a part ("to the side"), derived from Latin ad (to) + partem (part). Originally meant "separate" or "set aside."
  • ment: A noun-forming suffix from Latin -mentum, indicating the result or means of an action.

Etymology Origin:
The word "apartment" entered English in the 17th century from French appartement, which referred to a private suite of rooms in a palace. The Latin roots ad partem ("to the side") reflect the idea of a space separated for individual use. Over time, it shifted from luxury dwellings to general rental units, retaining the core concept of division.
