Questions & Answers about Он наверняка уже спит, потому что в его комнате темно.
What does наверняка mean here? Is it the same as probably?
Наверняка means something like for sure, certainly, almost certainly, or surely.
In this sentence, it does not mean absolute mathematical certainty. It expresses a strong conclusion based on evidence:
- Он наверняка уже спит = He’s surely/almost certainly asleep already
Compared with probably, наверняка usually sounds stronger.
- Он, наверное, уже спит = He’s probably already asleep
- Он наверняка уже спит = He’s almost certainly already asleep
So the speaker is not just guessing casually; they feel fairly confident.
Why is уже used? What does it add?
Уже means already.
So:
- Он спит = He is sleeping / He sleeps
- Он уже спит = He is already sleeping / He is asleep already
It tells us that the action or state has already begun by this point. In this sentence, the idea is: based on the darkness in his room, the speaker thinks he has already gone to sleep.
Why does спит mean is sleeping and not just sleeps?
