synagogue: [12] A synagogue is etymologically an ‘assembly’. The word comes via Old French sinagoge and late Latin synagōga from Greek sunagōgé ‘meeting, assembly’. This was a derivative of sunágein ‘bring together’, hence ‘assemble’, a compound verb formed from the prefix sun- ‘together’ and ágein ‘lead, drive’. Its specific application to an assembly for Jewish worship was introduced by early Greek translators of the Old Testament. => act, agent[synagogue etymology, synagogue origin, 英语词源]
