Morphology

proportional = proportion (transparent) = proportion + al

The adjective is a regular derivation from the noun 'proportion' with the suffix '-al', and the meaning is directly recoverable.

Etymology

The word proportional comes from the Latin parts pro- and portio, where portio means 'part' and is the same root as the English word portion. So, when two things are proportional, their 'parts' or amounts change together in the same way, which is why we use the word in math and when comparing amounts.
