analogous has 1 distinct synonym 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. Its 2 recorded opposites are homologous, heterologous.
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.
similar or equivalent in some respects though otherwise dissimilar
“brains and computers are often considered analogous”
corresponding in function but not in evolutionary origin
“the wings of a bee and those of a hummingbird are analogous”
