Breakdown of Уже пора идти спать, потому что завтра утром экзамен.
Questions & Answers about Уже пора идти спать, потому что завтра утром экзамен.
Пора is a predicative word meaning it’s time (to…). In sentences like this, Russian often uses an impersonal construction with no explicit subject:
- Пора идти спать. = It’s time to go to sleep. If you want, you can add a subject for emphasis:
- Мне пора идти спать. = It’s time for me to go to sleep.
- Нам пора идти спать. = It’s time for us to go to sleep.
Уже means already and commonly comes right before what it modifies:
- Уже пора… = It’s already time… Other placements are possible with slightly different emphasis:
- Пора уже идти спать. (more like it’s time already / a bit more insistent) Both are natural; the given order is very neutral.
Because спать is an infinitive (to sleep), not a place. Идти спать is a fixed, natural pattern meaning go to sleep / go to bed (to sleep). If you use a noun like кровать (bed) as a place, then you’d use a preposition:
- идти в кровать is not idiomatic; Russians would say идти в спальню (go to the bedroom) or more naturally ложиться в кровать (lie down in bed). Most often:
- идти спать = focus on the action (sleeping)
- идти в спальню = focus on the location (bedroom)
Both can work, but they feel different:
- пора идти спать sounds like a general “it’s time to be heading to sleep” (process-oriented, neutral).
- пора пойти спать emphasizes starting the action / setting off (more “time to go (now)”). In practice, пора идти спать is extremely common and idiomatic.
They’re close, but not identical:
- идти спать = to go (off) to sleep / to go to bed (the movement/decision to go)
- ложиться спать = to lie down to sleep / to go to bed (physically lying down) Example difference:
- Я пойду спать. = I’m going to bed (I’m leaving to go sleep).
- Я ложусь спать. = I’m lying down / turning in for the night (the act of getting into bed).
Because потому что introduces a subordinate clause giving the reason (because…). In Russian, a subordinate clause is normally separated by a comma:
- …, потому что завтра утром экзамен. This is standard punctuation, like the comma often used before because in more formal English writing.
In your sentence it’s correctly потому что (a fixed conjunction) meaning because. Потому, что (with a comma) can happen when потому is used as for that reason and что starts a separate clause—this is a different structure and meaning. For learners, the key takeaway is:
- потому что = the normal because
Утром is the instrumental case form of утро, used adverbially to mean in the morning. Common time expressions work the same way:
- утром (in the morning)
- днём (in the daytime)
- вечером (in the evening)
- ночью (at night)
Yes. Russian often omits быть (to be) in the present tense, and in many contexts it also omits it when the time is clear.
- завтра утром экзамен = (literally) “tomorrow morning (there is) an exam”
- завтра утром будет экзамен = explicitly “tomorrow morning there will be an exam” Both are correct; the version without будет sounds more direct and conversational.
Russian often uses a zero copula (no is/are) in the present, and can also use a verbless structure in time statements when the meaning is obvious:
- Завтра экзамен. = Tomorrow (there’s) an exam. If you want to make it explicit or more formal, add:
- Завтра будет экзамен.
Yes, Russian word order is flexible, and changes emphasize what’s important:
- …потому что завтра утром экзамен. (neutral: time first, then event)
- …потому что экзамен завтра утром. (slightly more focus on экзамен)
- …потому что завтра утром будет экзамен. (more explicit, slightly more formal)
Common pronunciation notes:
- идти: the д is often not clearly heard; it sounds close to итти. Stress is on the last syllable: идтИ.
- потому что: stress on -му- in потому́; что is often pronounced more like што in casual speech. Approximate stress marks:
- УжЕ порА идтИ спАть, потомУ что зАвтра Утром экзамЕн.
