"You are my real friend."

Translation: Jesteś moją prawdziwą przyjaciółką.

[Alexander577428]

Przyjaciółka can be used as both female friend and girlfriend?

[Vengir]

The first one. A girlfriend in Polish is „dziewczyna” – same as girl.

[brod1960]

Couldn't his be translated in the masculine as well?

[immery]

yes. then it is "jesteś moim prawdziwym przyjacielem"

[immerweiter]

Jesteś mojem prawdziwym przyjacielem

[immery]

*moim

[immerweiter]

thank you very much dziekuje bardzo

[orisi2]

If przyjaciółka can in some sense be rendered as girlfriend, then it is an ambiguous answer to say it can be only as friend.

[Jellei]

If you call your girlfriend "przyjaciółka", I guess you also have "it's complicated" as your relationship status on Facebook. Yeah, I guess someone may say that, just like someone can call his girlfriend "friend" in English, but that's absolutely not a translation.

[WarsawWill]

Would I be right in thinking that you were actually using "impersonal you" here, and were in fact referring to a hypothetical Facebook account, not the poster's?

[Jellei]

I do not remember, but let's hope so.

Why not "Pan jest moim prawdziwym przyjacielem.". ?

[Jellei]

No reason, the formal forms are still missing from some sentences. Added.

Well, frankly, it's not exactly common to use Formal You with a 'real friend', but it's not 'wrong'. My thought is about two elderly politicians who still address each other "Mr. Kowalski" and "Mr. Nowak" but they do discuss private matters and like each other's company.

[GP62HE]

You are my true friend

[alik1989]

...is an accepted answer.

Why kolega doesn't work here?

[Jellei]

I think this is a good sentence to show that although "kolega" can definitely be translated as "friend", there is a difference between "kolega" and "przyjaciel", and "przyjaciel" should be one of your closest friends. So "a true/real friend" seems to call for "przyjaciel" rather than "kolega".
