Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid calquing as 'цинковый оксид' in overly technical everyday speech; 'окись цинка' is also common. The English term is a compound noun, not an adjective-noun phrase like 'цинковая окись'.
Common Mistakes
- Misspelling as 'zinc oxcide' or 'zinc oxid'. Using it as a countable noun (e.g., 'a zinc oxide') is incorrect; it's a non-count mass noun.
