anthemyoudaoicibaDictYouDict[anthem 词源字典]
anthem: [OE] Anthem is ultimately an alteration of antiphon ‘scriptural verse said or sung as a response’ (which was independently reborrowed into English from ecclesiastical Latin in the 15th century). It comes from Greek antíphōnos ‘responsive’, a compound formed from anti- ‘against’ and phōné ‘sound’ (source of English phonetic, telephone, etc).

By the time it had become established in Old English, antiphon had already developed to antefn, and gradually the /v/ sound of the f became assimilated to the following n, producing antemne and eventually antem. The spelling with th begins to appear in the 15th century, perhaps influenced by Old French anthaine; it gradually altered the pronunciation.

The meaning ‘antiphon’ died out in the 18th century, having been succeeded by ‘piece of choral church music’ and more generally ‘song of praise’. The specific application to a ‘national song’ began in the 19th century.

symphonyyoudaoicibaDictYouDict
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).
