packaging has 4 distinct synonyms spread across 1 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.
the business of packing
“his business is packaging for transport”
a message issued in behalf of some product or cause or idea or person or institution
“the packaging of new ideas”
Synonyms, antonyms and the broader and narrower relations for packaging come from Princeton University’s WordNet. Full sources and licences.
