eight-member

The compound adjective 'eight-member' is a modern English formation built from two distinct and ancient roots. The first element, 'eight', descends from the Proto-Indo-European root oḱtṓw, which gave rise to the Proto-Germanic ahtōu and eventually the Old English eahta. The second element, 'member', traces back to the Latin membrum, meaning a limb or part of a body, which itself may derive from a Proto-Indo-European root meaning 'flesh'. The logic of the compound is transparent and numerical, directly combining the quantity 'eight' with the concept of a constituent part ('member') to specify the exact size of a group, team, or committee. This pattern of number-plus-noun compounding is a productive and straightforward method in English for creating precise descriptive terms.
