Morphology
hydrous = hydrate (transparent) = hydr + ous
Meaning 'containing water' follows directly from the combining form 'hydr-' (water) plus the adjectival suffix '-ous', which learners familiar with 'hydrate' or 'hydro-' can infer.
Etymology
Hydrous comes from the Greek root hydr-, from hydor, which means 'water', and you can see the same root in hydrate and hydrogen, so a hydrous mineral contains water inside it.
