Morphology

clinal = cline (semi-transparent) = cline + al

The adjective is formed regularly from the noun 'cline', but the scientific/geographic sense is specialized and not fully predictable for an average learner.

Etymology

Clinal comes from the Greek root klinein which means 'to lean', and it is the same root as in incline. Think of a slow change up a hill where plants slowly shift as you climb — that's a 'clinal' change, a gradual shift across a region.
