Etymology

It is borrowed from Ancient Greek συνώνυμον (sunṓnumon), neuter of συνώνυμος (sunṓnumos, “having the same name”), from σύν (sún, “with”) and ὄνομα (ónoma, “name”).[2][1][3]

Earliest recorded meaning

Lewis & Short and Köbler cite Fronto, whom Köbler dates 100–170 AD.[4][5]

Semantic evolution

It was a word with the same meaning as another, a synonym, in Fronto and the grammarians Priscian and Servius.[2][4]

English synonym (early 15th century) came through Old French synonyme and directly from Late Latin synōnymum.[3] It survives in Italian sinonimo and Spanish sinónimo.[1]
