Pentaplex

Part of speech: noun

Definitions

1. A residential building containing five separate dwelling units, each typically with its own entrance and independent living facilities
2. A structure designed to accommodate five individual living spaces, each offering its own entrance and complete residential amenities
3. This architectural form consists of five distinct units meant for separate habitation, complete with private access and facilities

Etymology: "Pentaplex" is built from two parts: the Greek prefix "penta-", meaning "five", and the Latin-derived suffix "-plex", as in "duplex" (two-fold) and "triplex" (three-fold). Put together, the word describes a building of five units, the way a duplex houses two households under one roof. The pattern is a deliberate piece of architectural naming rather than an old inherited term. Builders and planners applied the familiar "-plex" ending, borrowed from the Latin for "fold" in words like "simplex" and "multiplex", to a count of five, producing a compact label for a block of five separate dwellings, each with its own entrance and facilities.
