* Спасибо (Spasibo): This is the most common and general way to say thank you. It's appropriate for most situations.
Informal:
* Спасибо большое (Spasibo bolshoe): This means "Thank you very much" and is a bit more emphatic than just "спасибо."
* Благодарю (Blagodaryu): This is a more formal way to say thank you, and is often used in more official settings.
* Спасибо тебе (Spasibo tebye): This means "Thank you" and is used when addressing someone directly.
The Cyrillic script is used in various languages like Russian, Bulgarian, Serbian, and Ukrainian. So, the pronunciation of "thank you" might vary slightly depending on the language.
