Hello forum members,
My question is, when do you use the word "является" in Russian? It means "Is", but for some sentences you don't use it, like in "Это хорошо," or "Не так ли?" But for sentences such as "Она является христианка." (Please correct me on that sentence if I'm wrong) you can include it. So Please tell me when you have to/can use it; thank you!
