Morphology

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

The form is the same derivation as the general noun (correlate + -ion); the structural formation is regular and clear.

Etymology

Correlation comes from the parts co- 'together' and relation 'connection', the same root as the common word relation. A helpful image is two things that 'move together', because if they go up or down at the same time they have a strong correlation. So in statistics, a correlation is a number that tells how much two things change together.
