Morphology

unbreathable = breathable (transparent) = un + breathe + able

The adjective is formed by adding the productive prefix 'un-' to 'breathable', producing the direct opposite meaning.

Etymology

Unbreathable is made from un- ('not'), breathe ('to breathe') and -able ('able'). Think of a plastic raincoat that will not let air or moisture through so you feel hot and sticky, so unbreathable means 'not allowing air or moisture to pass through' and is uncomfortable to wear.
