subordination has 2 distinct synonyms spread across 2 of its 5 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 one recorded opposite is insubordination.
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 state of being subordinate to something
the semantic relation of being subordinate or belonging to a lower rank or class
the grammatical relation of a modifying word or phrase to its head
the quality of obedient submissiveness
