silicaceous
|sil-i-ca-ceous|
/ˌsɪlɪˈkeɪʃəs/
containing or made of silica
Etymology
'silicaceous' originates from Late Latin, specifically the word 'silicaceus,' where 'silica' referred to 'silica' or 'flint' and the suffix '-aceus' meant 'of or pertaining to.'
'silicaceus' developed from Latin 'silica' (from earlier 'silex, silicis' meaning 'flint') plus the adjectival suffix '-aceus', and passed into New Latin/English as 'silicaceous'.
Initially it meant 'pertaining to or like flint/silica'; over time it came to mean 'consisting of or containing silica; siliceous' in modern usage.
