1. Transliteration:
The most common way is to transliterate the name, which means using the closest-sounding Russian letters: Ребекка (Rebekka)
2. Adaptation:
You could also adapt the name to sound more Russian, such as:
* Ребэка (Rebeka)
* Ребека (Rebeka)
3. Other options:
If you prefer a completely Russian name, you could consider using a name with a similar meaning, such as:
* Раиса (Raisa) - meaning "from the people"
* Рина (Rina) - meaning "song"
The best choice will depend on your context and personal preference.
