Questions & Answers about Спасибо всем, кто пришёл на спектакль.
Всем is the dative plural form of все (everyone / all).
- все – nominative plural: all, everyone
- всем – dative plural: to all (of you/them)
In Russian, when you say Спасибо, the person you’re thanking is normally in the dative case:
- Спасибо маме. – Thanks to mom. (мама → маме, dative)
- Спасибо друзьям. – Thanks to (my) friends. (друзья → друзьям, dative)
- Спасибо всем. – Thanks to everyone. (все → всем, dative plural)
So всем is “to everyone,” matching the pattern Спасибо + dative.
Russian very often drops the subject я when it’s obvious from context or grammar.
Also, Спасибо behaves like a fixed expression “Thank you,” not like a full verb sentence. You can think of it as an elliptical structure like:
- Спасибо (вам). – (I say) thank you (to you).
You can use a full verb:
- Я благодарю всех, кто пришёл на спектакль. – I thank everyone who came to the performance.
But in everyday speech and writing, Спасибо всем, … is more natural and less formal than Я благодарю всех, ….
