The word *antonym* is younger than the word *synonym* by roughly three centuries — *synonym* entered English in the 1580s from Latin and Greek.

attested in the Indo-European family: Latin 'nomen,' Sanskrit 'nāman,' Old English 'nama' (Modern English 'name'), Gothic 'namo,' Armenian 'anun,' and Old Church Slavonic 'imę' all descend from the same PIE source. The compound 'antōnumia' (ἀντωνυμία) actually existed in ancient Greek but meant something entirely different — it was the grammatical term for 'pronoun' (a word used instead of a name/noun), used by Greek grammarians like Dionysius Thrax in the 2nd century BCE. Smith repurposed the component morphemes rather than borrowing any ancient compound directly. Key roots: *h₂enti (Proto-Indo-European: "in front of, opposite, facing; source of Greek anti-, Latin ante, Sanskrit ánti"), *h₃nómn̥ (Proto-Indo-European: "name; source of Greek onoma/onyma, Latin nomen, Sanskrit nāman, Old English nama"), anti- (ἀντί) (Ancient Greek: "against, opposite, instead of, in place of"), onyma / onoma (ὄνυμα / ὄνομα) (Ancient Greek: "name, word; used in grammatical compounds such as antōnumia (pronoun) and synonymia (synonym)").
