How do you say Russian princess in Russian?

There isn't a direct translation for "Russian princess" in Russian. Here's why and how you can say it:

* Formal/Historical:

* Русская княжна (Russkaya knyazhna) - This is the most formal and historically accurate way to refer to a princess of a Russian principality (княжество, knyazhestvo) in the past.

* Modern Usage:

* Русская принцесса (Russkaya printsessa) - While technically "принцесса" refers to a princess in general, it's the most common way to say "Russian princess" in modern usage.

* Княгиня (Knyaginya) - This term can be used for a female member of a royal family, but it doesn't specifically mean "princess."

The best option depends on the context:

* For historical contexts: use "Русская княжна."

* For modern contexts: use "Русская принцесса."

Remember, the use of "принцесса" can sometimes be informal, but it's understood in most contexts.
