Morphology

defog = fog (transparent) = de + fog

The prefix 'de-' clearly means removal here, so 'defog' straightforwardly means to remove fog or mist from something.

Etymology

Defog is made from the prefix de- meaning 'remove' and fog meaning 'a cloud of tiny water drops', so it literally means 'remove fog'. That's why to defog a mirror or window is to clear the mist so you can see.
