IPA: /ˌsɪlɪkɪfɪˈkeɪʃən/
KK: /sɪlɪkɪfɪˈkeɪʃən/
The process of being filled or replaced with silica, often leading to the hardening of materials like wood or bone into a stony substance.
The silicification of the wood turned it into a fossil over millions of years.
Silicification is formed from "silica" (from Latin *silica*, meaning flint or silica) and "-fication" (from Latin *facere*, meaning to make or to do). The word describes the process of making something into silica or converting it into a siliceous form.
Think of 'silica' as the material being transformed and '-fication' as the process of making. This helps you remember that silicification means the process of turning something into silica.
