single-family

The compound adjective 'single-family' is a modern real estate and zoning term, formed by directly combining two English words of Latin origin. 'Single' traces back to Latin singulus, meaning 'one, individual, separate', which itself may derive from a Proto-Indo-European root meaning 'one'. 'Family' originates from Latin familia, referring to the entire household, including servants and kin under one head. The logic of the compound is transparently literal: 'one household', specifying a residential building intended for occupancy by a single, self-contained domestic unit, distinct from multi-family dwellings like duplexes or apartment buildings.

Structure: single (one) + family (household) - single: From Latin singulus (one, individual). Functional role: Adjective modifier meaning 'one' or 'individual'. - family: From Latin familia (household, servants of a household). Functional role: Noun root denoting a domestic unit.
