Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'cyanide' (цианид). It is unrelated. The 'kyan' refers to a person's name. There is no direct Russian equivalent; a descriptive translation like 'обрабатывать древесину по способу Каяна' or 'обрабатывать сулемой' might be used historically.
Common Mistakes
- Misspelling as 'cyanize' (which would relate to cyanide).
- Using it as a general synonym for 'waterproof' or 'preserve'.
- Assuming it is a current technical term.
