The quality or state of being correlative; the degree to which things are mutually dependent or connected.
From correlative (adjective) plus the abstract noun suffix -ness, which forms nouns describing qualities or states. A philosophical term that emerged in formal discourse.
Correlativeness is a big word philosophers love because it captures the idea that some things only make sense as a pair—you can't have 'up' without 'down,' proving language itself is built on relationships.
