words has 9 distinct synonyms spread across 3 of its 5 senses. Each sense below keeps its own list, because a synonym belongs to a meaning and not to a word: swapping one sense's substitute into another sense's sentence is how a thesaurus makes writing worse. WordNet records no antonym for it — antonymy is a relation between word forms rather than concepts, so it is deliberately sparse.
Counts are distinct word forms across every sense. A synonym that appears under three senses is counted once here and shown three times below, under each sense it belongs to.
the words that are spoken
“I listened to his words very closely”
the text of a popular song or musical-comedy number
“his compositions always started with the lyrics”
language that is spoken or written
“he has a gift for words”
Synonyms, antonyms and the broader and narrower relations for words come from Princeton University’s WordNet. Full sources and licences.
