Morphology

correlation = correlate (transparent) = cor + relate + ion

Formed by the verb 'correlate' + the noun-forming suffix '-ion'; the relation to 'relate' and the idea of mutual relationship is clear.

Etymology

Correlation comes from the parts co- 'together' and relation 'connection'. Think of it as two things that 'relate together', so when one changes the other often changes too. So a correlation is a link that shows how two or more things change together.
