current account has 2 distinct synonyms spread across 1 of its 2 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.
that part of the balance of payments recording a nation's exports and imports of goods and services and transfer payments
a bank account against which the depositor can draw checks that are payable on demand
Synonyms, antonyms and the broader and narrower relations for current account come from Princeton University’s WordNet. Full sources and licences.
