translation has 5 distinct synonyms spread across 3 of its 7 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.
a written communication in a second language having the same meaning as the written communication in a first language
a uniform movement without rotation
the act of changing in form or shape or appearance
“a photograph is a translation of a scene onto a two-dimensional surface”
(mathematics) a transformation in which the origin of the coordinate system is moved to another position but the direction of each axis remains the same
(genetics) the process whereby genetic information coded in messenger RNA directs the formation of a specific protein at a ribosome in the cytoplasm
rewording something in less technical terminology
Synonyms, antonyms and the broader and narrower relations for translation come from Princeton University’s WordNet. Full sources and licences.
