defective


defective
defective, deficient
Defective means ‘having a defect (= fault)’, whereas deficient means ‘having a deficiency (or lack)’. So eyesight, components, goods, logic, mechanisms, products, workmanship, etc., can all be defective if they are not working or done properly; and courage, diet, funds, protein, the water supply, etc., can all be deficient if there is not enough of them. Neither word is used any longer in professional contexts relating to mental abnormality, but defective gene is a standard term in genetics.
