Common Pitfalls
Translation Traps (for Russian speakers)
- Do not translate as "девяносто девять" and then add a noun in the singular genitive case. In English, the noun is plural after a number >1 (e.g., "ninety-nine books", not "ninety-nine of book").
- Be careful with word order in prices: "two ninety-nine" means £2.99, not 299.
Common Mistakes
- Writing it as 'ninty-nine' (misspelling 'ninety').
- Saying 'ninety nine' without the hyphen when used as a compound adjective before a noun (e.g., a ninety-nine-year lease).
