Morphology

covariation = covary (transparent) = co + vary + ation

Formed by adding the noun-forming suffix '-ation' to the verb 'covary' (co- + vary), producing a noun meaning the act or degree of varying together.

Etymology

The word covariation comes from co- meaning 'together' and variation, from vary meaning 'to change'. So covariation means how much two things change together, which is exactly what it describes in statistics.
