Morphology

defective = defect (transparent) = defect + ive

Meaning is directly derived from 'defect' + the adjectival suffix '-ive', indicating 'having a defect' in the usual sense for learners.

Etymology

Defective comes from Latin parts de- meaning 'away' and fect (from facere) meaning 'to make', and you can see the same fect in perfect ('well made'). So a defective product is 'not made right' and has a fault that keeps it from working properly.
