Morphology

faulty = fault (transparent) = fault + y

The word 'faulty' is transparently derived from 'fault' with the addition of the suffix '-y' to form an adjective.

Etymology

Faulty comes from the word fault, which comes from an old French word faute meaning 'error' or 'lack', and the ending -y means 'having' or 'full of'. So faulty means 'having a fault', which is why we call brakes, wires, or parts 'faulty' when they do not work correctly.
