Morphology

effective = effect (transparent) = effect + ive

Standard adjective formation from 'effect' + '-ive' meaning 'producing a result', which learners can derive from the base.

Etymology

Effective comes from effect ('a result') plus the Latin root facere ('to make'), the same root you see in factory. So effective really means 'making a result', which is why an effective speech or medicine produces the result you want.
