nonmember

The word 'nonmember' is a modern English compound formed by straightforward combination. The prefix 'non-' descends from the Latin adverb non, meaning "not," a definitive negative particle. The root 'member' entered English via Old French membre from Latin membrum, which originally referred to a limb or a distinct part of a body. By metaphorical extension, this evolved to mean an individual constituent part of a collective body, such as a society or organization. Therefore, 'nonmember' logically constructs its meaning as "not a constituent part," directly applying the ancient Latin negative to the later, socially extended sense of 'member.'
