try has 20 distinct synonyms spread across 9 of its 10 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.
put on trial or hear a case and sit as the judge at the trial of
“The football star was tried for the murder of his wife”
give pain or trouble to

Synonyms, antonyms and the broader and narrower relations for try come from Princeton University’s WordNet. Full sources and licences.
