dislocation has 2 distinct synonyms spread across 2 of its 3 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.
an event that results in a displacement or discontinuity
the act of disrupting an established order so it fails to continue
“the social dislocations resulting from government policies”
a displacement of a part (especially a bone) from its normal position (as in the shoulder or the vertebral column)
Synonyms, antonyms and the broader and narrower relations for dislocation come from Princeton University’s WordNet. Full sources and licences.
