crewman
noun （pl. -men）词源
late Middle English:from Old French creue 'augmentation, increase', feminine past participle of croistre 'grow', from Latin crescere. The original sense was 'band of soldiers serving as reinforcements'; hence it came to denote any organized armed band or, generally, a company of people （late 16th cent.）.
