double-occupancy

The term is a modern compound noun formed within English from two pre-existing words. 'Double' originates from the Latin duplus, meaning "twofold," which itself derives from the Proto-Indo-European root \dwo-, the source for the concept of "two." 'Occupancy' comes from the Latin verb occupare, meaning "to seize or possess," built from ob- (over) and capere (to take). In the context of hospitality and real estate, 'occupancy' evolved to mean the act of residing in or using a space. The compound 'double-occupancy' logically combines these elements, specifying a rate or arrangement for the occupation of a room by two persons, a straightforward numerical qualification of a standard industry term.

In this compound, it functions as a modifier specifying quantity. occupancy: From Latin occupare (to seize, possess) via the derived noun occupantia.
