exact has 5 distinct synonyms spread across 3 of its 4 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. Its one recorded opposite is inexact.
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.
take as an undesirable consequence of some event or state of affairs
“the accident claimed three lives”
marked by strict and particular and complete accordance with fact
“an exact mind”
Synonyms, antonyms and the broader and narrower relations for exact come from Princeton University’s WordNet. Full sources and licences.
