Questions & Answers about В выходные дни я могу спать допоздна.
Why is выходные in the plural form?
Because “weekends” in Russian literally means the two (or more) days off in a row, so you always treat выходные as plural. It’s like saying “weekends” rather than “weekend.”
What case is выходные дни, and why is it used with в?
The phrase в выходные дни uses the accusative case for a time expression. In Russian, в + accusative often indicates “during” or “in” a span of time (e.g. в выходные дни = “during the weekend days”).
What’s the difference between в выходные дни, на выходных, and по выходным?
- в выходные дни is a bit more formal or bookish (“on the weekend days”).
- на выходных is the most common colloquial way to say “on weekends.”
- по выходным emphasizes “on each weekend” as a habitual action.
All three are correct; choose by style and nuance.
Why do we use я могу instead of я смогу?
я могу is the present-tense ability (“I can/I’m able to sleep in”).
я смогу is the perfective future (“I will be able to”). If you want to stress “I will be able to sleep late next weekend,” you could say на следующих выходных я смогу спать допоздна, but in a general statement about weekends one uses the present tense.
Why is спать in the imperfective, not поспать (perfective)?
Imperfective спать describes a habitual or ongoing possibility (“to be able to sleep in regularly”). Perfective поспать would imply a one-off completed action (“to manage to sleep a bit”), which sounds odd in a general habit sentence.
What does допоздна mean, and is it an adjective or adverb?
допоздна means “until late” or “late in the morning.” It’s an indeclinable adverb formed from до + поздно. It never changes its form.
Can I change the word order to я могу допоздна спать?
Yes. Both я могу спать допоздна and я могу допоздна спать are grammatically correct. Moving the adverb допоздна before спать slightly shifts the emphasis onto how late you sleep, but the meaning remains the same.
How would you say “I like to sleep in on weekends” in Russian?
You can say: по выходным я люблю спать допоздна. Here по выходным highlights the habitual weekend action, and люблю means “I like.”
