1375, from O.Fr.
communité, from L.
communitatem (nom.
communitas) "community, fellowship," from
communis "common, public, general, shared by all or many," (see
common). L.
communitatem "was merely a noun of quality ... meaning 'fellowship, community of relations or feelings,' but in med.L. it was, like
universitas, used concretely in the sense of 'a body of fellows or fellow-townsmen' " [OED]. An O.E. word for "community" was
gemænscipe "community, fellowship, union, common ownership," probably composed from the same PIE roots as
communis.
