Morphology

hydrophobic = phobic (semi-transparent) = hydro + phobic

The chemical sense extends the literal idea of 'water-fearing' to 'repelling water', so the form is recognizable but the specialized meaning is not fully predictable.

Etymology

Hydrophobic comes from the Greek parts hydro- 'water' and -phobic 'afraid', so it literally means 'water-fearing' and is used for materials or coatings that push water away or do not mix with it.
