single-member

The compound adjective 'single-member' is a modern, transparent construction built from two ancient roots. 'Single' traces back to the Latin singulus, meaning one and only, which itself may derive from a Proto-Indo-European root meaning 'one' combined with a diminutive suffix. 'Member' originates from the Latin membrum, referring literally to a limb of the body, a concept extended metaphorically to any distinct part of a larger structure. The logic of the compound is direct and literal: 'one-part' or 'having one constituent', a meaning that cleanly bridges the ancient senses of its components to its contemporary administrative and organizational usage.

Structure: single (one) + member (constituent part) - single: From Latin singulus (one, individual, separate). Functions as an adjective meaning 'one only'. - member: From Latin membrum (limb, part of the body). Functions as a noun meaning 'a constituent part of a whole'.
