symphony: [13] Symphony originally meant ‘harmony’; it was not used for a ‘large-scale piece of orchestral music in several movements’ until the late 18th century. The word came via Old French symphonie and Latin symphōnia from Greek sumphōníā, a derivative of súmphōnos ‘harmonious’. This was a compound adjective formed from the prefix sun- ‘together’ and phōné ‘sound’ (source of English phone, phonetic, etc). => phone, phonetic[symphony etymology, symphony origin, 英语词源]
