greece 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.
a republic in southeastern Europe on the southern part of the Balkan peninsula; known for grapes and olives and olive oil
ancient Greece; a country of city-states (especially Athens and Sparta) that reached its peak in the fifth century BCE
