five-member

The compound adjective 'five-member' is a transparent modern English formation. Its first element, 'five', originates from the Proto-Germanic 'fimf', which can be traced back to the Proto-Indo-European root 'penkwe-', the source for the number five across many languages. The second element, 'member', derives from Latin 'membrum', meaning a limb or part of a body, which metaphorically extended to mean any constituent part of a group or structure. The compound logically combines these elements to denote a group or entity composed of exactly five such constituent parts, following a common English pattern for creating descriptive adjectives.
