Questions & Answers about Сегодня мне плохо, поэтому я остаюсь дома.

Why does it say мне плохо and not я плохо?

Because плохо here is used as a state (“I feel bad / I’m unwell”), and Russian commonly expresses states with a dative person + category-of-state word:

  • мне (to me / for me) + плохо (bad, unwell)
    So мне плохо = “I’m not feeling well.”

Я плохо is incomplete; it would need a verb or be part of something like я плохо себя чувствую (“I feel bad”).


What exactly does плохо mean here—“badly,” “bad,” or “sick”?

Literally, плохо is “badly,” but in this structure (мне плохо) it means “I feel bad / I’m unwell.” It’s broader than “sick” and can cover:

  • illness
  • nausea, weakness
  • emotional distress
    If you want explicitly “I’m sick (ill),” you might say я болею or я болен/больна.

Why is мне in the dative case?

The dative marks the experiencer of a state in many Russian expressions:

  • мне холодно (I’m cold)
  • мне жарко (I’m hot)
  • мне грустно (I’m sad)
  • мне плохо (I feel unwell)
    So мне is dative because the feeling/state is “happening to” you.

What role does поэтому play, and how is it different from потому что?
  • поэтому = “therefore / so,” it introduces the result:
    Сегодня мне плохо, поэтому я остаюсь дома. = “..., so I’m staying home.”
  • потому что = “because,” it introduces the reason:
    Я остаюсь дома, потому что мне плохо. = “I’m staying home because I feel unwell.”

They often pair conceptually:

  • потому что → cause
  • поэтому → consequence

Is the comma before поэтому required?

Yes, typically. поэтому connects two independent parts (two clauses), so you normally write a comma:

  • Сегодня мне плохо, поэтому я остаюсь дома.

Why is it я остаюсь дома (present tense) if it refers to “today”?

Russian often uses the present tense to describe a current decision or ongoing situation:

  • “Today I feel unwell, so I’m staying home.” (right now / as a plan for today)

It can describe either:

  • what is happening now (you are staying home)
  • an immediate decision/plan (you will stay home)

What’s the difference between я остаюсь дома and я останусь дома?
  • я остаюсь дома (imperfective) = “I’m staying home / I stay home (today)” (process/ongoing/arrangement)
  • я останусь дома (perfective) = “I will stay home / I’ll remain at home” (a single decision/result)

In this context both can work, with a slightly different feel:

  • остаюсь = more “I’m staying (as my current course of action)”
  • останусь = more “I’ll stay (decision / final outcome)”

Why is дома used instead of в доме?

дома is an adverb meaning “at home.” It’s the most natural choice for “stay home”:

  • я остаюсь дома = “I’m staying home.”

в доме means “in the house/building” and sounds more physical/specific:

  • я остаюсь в доме = “I’m staying in the house (not going outside).”

Does сегодня have to be first in the sentence?

No. Word order is flexible, and moving сегодня changes emphasis:

  • Сегодня мне плохо... = emphasis on “today”
  • Мне сегодня плохо... = emphasis on “to me / my condition,” with “today” added
  • Мне плохо сегодня... = “today” can sound more contrastive (“today (as opposed to other days)”)

The meaning stays basically the same.


Could you omit я and just say ... поэтому остаюсь дома?

Yes, often. Russian can drop the subject pronoun when it’s clear:

  • Сегодня мне плохо, поэтому остаюсь дома.
    This is common in speech and informal writing.

Keeping я adds emphasis or clarity.


What does оставаться literally mean, and why is it used here?

оставаться means “to remain / to stay (behind) / to continue being somewhere.” In everyday Russian it’s a normal way to say “stay home” in the sense of “not going out”:

  • остаюсь дома = “I’m staying at home (not going anywhere).”

Another option is сидеть дома (“to sit at home”), which can sound more like “to be home doing nothing / stuck at home,” depending on context.
