Etymology of Synonyms and Antonyms

The words synonym and antonym come from Greek. Both words have been used in English for many years to describe relationships between words.

Period	Historical Development
Old English (450–1100)	English speakers used native words to describe similar and opposite ideas. The modern terms synonym and antonym were not part of everyday Old English vocabulary.
Middle English (1100–1500)	English gained many words from French and Latin. The study of word meanings grew as English vocabulary developed.
Modern English (1500–Present)	Synonym came from Greek roots meaning “same name,” while antonym came from Greek roots meaning “opposite name.” Both are now common terms in language learning.

These terms help us understand how words connect and differ in meaning.
