Pronunciation
- IPA: /ˈsɪn.əˌnɪm/[1]
Etymology
It is inherited from Middle English sinonyme, borrowed from Middle French synonyme,[2][3][4] and directly from Latin synōnymum,[2][3][4][5][6] from Ancient Greek συνώνυμον (sunṓnumon, “word with the same sense”), the neuter of sunṓnumos “having the same name”,[2][3][4][5][6] from Ancient Greek σύν (sún, “together, same”) + ὄνυμα (ónuma, “name”), the latter an Aeolic form of ónoma.[3][4][5]
Earliest recorded meaning
A word having the same sense as another in the same language (1432–50 in the OED; before 1425 in Barnhart, as the plural sinonymes).[7][3]
Semantic evolution
Until the 18th century the word was usually used in the plural, synonymes or synonyma, and the modern singular rarely appears before the end of that century except in dictionaries.[3][4] From 1631 it also meant a name or expression that implies or stands for something else, as when a person's name becomes a synonym for a quality.[7][5] In natural history a synonym is a scientific name applied to the same taxon as another (1659).[7][2]
