divergence has 7 distinct synonyms spread across 4 of its 4 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 convergence.
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 act of moving away in different direction from a common point
“an angle is formed by the divergence of two straight lines”
a variation that deviates from the standard or norm
“the deviation from the mean”
a difference between conflicting facts or claims or opinions
