Why no direct translation:
* Nikki is a shortened form of "Nicole" which is not a common Russian name.
* Russian names often have a different sound and structure than English names.
Possible options:
1. Николь (Nikol): This is the most common Russian spelling of Nicole. It's a direct transliteration and sounds similar to the English name.
2. Никки (Nikki): You could use the transliterated spelling, but it's not a common name in Russia and might be mispronounced.
3. Ника (Nika): This is a popular Russian name, meaning "victory," and could be a suitable alternative for Nikki.
4. Нюша (Nyusha): A less common but adorable Russian name that might work.
Ultimately, the best option depends on your specific context and preference.
