Morphology

unhydrated = hydrated (transparent) = un + hydrate + ed

Formed by adding the productive negative prefix 'un-' to 'hydrated' (having combined with water), so the meaning 'not combined with water' is directly derivable.

Etymology

Unhydrated breaks into un- 'not' and hydrate 'add water', the same root as hydrant. So an unhydrated powder or material is 'not combined with water' and must be mixed with water before use.
