Morphology

powerful = power (transparent) = power + ful

The adjective is a direct, regular formation from the noun 'power' with productive suffix '-ful' meaning 'having' or 'full of' power.

Etymology

Powerful comes from power ('ability to do or force') plus the ending -ful ('full of'), so it originally meant 'full of power'. Think of a strong engine or a heavy wind that has a lot of force, which is why we use it for physical strength.
