Morphology

directional = direction (transparent) = direction + al

The adjective is built directly from 'direction' with the common adjectival suffix '-al', so the meaning is straightforwardly related to direction.

Etymology

The word directional comes from direct and direction, which mean 'to guide' and 'the way'. So a directional microphone, antenna, or light is made to pick up or send sound or signals from one particular 'direction' rather than from all sides.
