Translation Traps (for Russian speakers)
- Avoid direct calques like *'кератинизировать'*; the standard Russian equivalent is ороговевать (orogovevat').
- Do not confuse with 'harden' (закаляться) in non-biological contexts.
Common Mistakes
- Misspelling as 'keritinize' or 'kertainize'.
- Using it as a general synonym for 'harden' outside biological contexts.
- Incorrect stress: /ˈkɛrətaɪn/ instead of /ˈkɛrətɪn/ for the root.
