Etymology
The word 'crewmember' is a transparent modern compound, formed by directly combining two established English nouns. 'Crew' has a fascinating journey from a concept of growth or reinforcement in Latin ('crescere') to a band of military recruits in Old French, eventually narrowing to its modern sense of a team operating a vehicle or vessel. 'Member' originates from the Latin 'membrum', literally a limb or bodily part, which metaphorically extended to mean a constituent part of any collective body. The compound 'crewmember' logically follows this metaphor, designating an individual who is a constituent part, or a functioning 'limb', of the operational crew.
Analysis
Structure: crew (group) + member (one belonging to a group)
crew: From Middle English 'creue', meaning 'reinforcement, increase', from Old French 'creue', based on the feminine past participle of 'croistre' (to grow), from Latin 'crescere' (to grow). In this word, it functions as a noun root meaning a group of people working together.
member: From Middle English 'membre', from Old French, from Latin 'membrum' (limb, part of the body). In this word, it functions as a noun root meaning an individual belonging to a larger body or group.
