Morphology

silicic = silica (transparent) = silic + ic

Formed from the combining element 'silic-' (from silica) plus the adjectival suffix '-ic', meaning 'relating to or containing silica', which is directly predictable for learners who know 'silica' and '-ic'.

Etymology

Silicic comes from the root silic-, the same root in silica and silicon, which originally came from a Latin word for 'flint' or 'hard stone'. So, silicic means 'containing silica' and is used for rocks and minerals that are rich in that hard, glass-like material.
