silicic
|si-lic-ic|
/sɪˈlɪsɪk/
relating to silica/silicon
Etymology
'silicic' originates from New Latin, specifically the word 'silicicus,' where 'silic-' referred to 'flint' or hard stone (silica).
'silicic' developed from Latin 'silicicus' (built on 'silex, silic-' meaning 'flint'), and was adopted into English in the 19th century as a technical chemical adjective relating to silica.
Initially it meant 'of or relating to flint (silica)'; over time it evolved into the current chemical and geological sense 'relating to silicon, silica, or silicic acid.'
