member


member
member (n.) late 13c., "sex organ" (Cf. L. membrum virile, but in English originally of women as well as men), also, "body part or organ" (in plural, "the body"), from O.Fr. membre "part, portion; topic, subject; limb, member of the body; member" (of a group, etc.)," 11c., from L. membrum "limb, member of the body, part," probably from PIE *mems-ro, from root *mems- "flesh, meat" (Cf. Skt. mamsam "flesh;" Gk. meninx "membrane," meros "thigh" (the "fleshy part"); Goth. mimz "flesh"). In English, sense of "person belonging to a group" is first attested early 14c., from notion of "constituent part of a complex structure." Meaning "one who has been elected to parliament" is from early 15c.
