Czy masz zamiar zostać w domu, jeśli jutro znowu będzie padać?

Czy marks a yes/no question. It does not mean a separate word like English do or whether here; it simply signals that the whole sentence is a question.

So:

• Masz zamiar zostać w domu. = You intend to stay at home.
• Czy masz zamiar zostać w domu? = Do you intend to stay at home?

In casual speech, Polish sometimes leaves czy out and relies on intonation:

• Masz zamiar zostać w domu?

But with learners, it is very useful to recognize czy as a common question marker.

Masz zamiar literally means you have the intention. It is used to express plan, intention, or what someone means to do.

So:

• Czy masz zamiar zostać w domu...? = Do you intend / are you planning to stay at home...?

This is a little different from simply asking whether the action will happen.

Compare:

• Czy zostaniesz w domu? = Will you stay at home?
  This asks more directly about the future action.
• Czy masz zamiar zostać w domu? = Do you intend to stay at home?
  This focuses on your present plan or decision.

So the Polish sentence is about intention, not just future fact.

Because the sentence asks about your current intention now.

Even though the action of staying home would happen tomorrow, the intention exists in the present:

• masz zamiar = you intend / you are planning

English does the same thing:

• Do you intend to stay home tomorrow?

We do not normally say Will you intend... because the intention is understood as something you have now.

Yes, zostać can mean to become, but it can also mean to stay / remain, depending on context.

In this sentence:

• zostać w domu = to stay at home

The phrase w domu makes the meaning clear. No Polish speaker would understand it here as become in the house.

Some common uses:

• zostać lekarzem = to become a doctor
• zostać w domu = to stay at home

So this is a good example of how one Polish verb can have more than one meaning depending on what follows it.

Both relate to being at home, but they are not exactly the same.

• być w domu = to be at home
• zostać w domu = to stay at home / remain at home

Zostać suggests remaining somewhere instead of going out or leaving. That is why it fits naturally with this sentence.

Compare:

• Jutro będę w domu. = Tomorrow I’ll be at home.
• Jutro zostanę w domu. = Tomorrow I’ll stay home.

The second one carries more of the idea of choosing not to go out.

Because after w meaning in, Polish uses the locative case, and the locative form of dom is domu.

So:

• dom = house/home
• w domu = in the house / at home

This is one of the very common noun patterns you just have to learn:

• w sklepie = in the shop
• w samochodzie = in the car
• w domu = at home

The form domie is not correct in standard Polish.

It is the locative case.

When w means in or at, it normally takes the locative:

• w domu = at home
• w szkole = at school
• w pracy = at work

Be careful: w does not always take the same case in every situation. For example, when movement is involved in some expressions, other structures may appear. But in a phrase like w domu meaning location, think locative.

Yes. Jeśli and jeżeli both mean if.

• jeśli is very common and neutral
• jeżeli is also correct, but often sounds a bit more formal or slightly more written

So these are both fine:

• Czy masz zamiar zostać w domu, jeśli jutro znowu będzie padać?
• Czy masz zamiar zostać w domu, jeżeli jutro znowu będzie padać?

For everyday conversation, jeśli is extremely natural.

Będzie padać is the future tense of the imperfective verb padać (to rain).

Polish often forms the future of imperfective verbs with:

• będę / będziesz / będzie / będziemy / będziecie / będą
  
  • infinitive

So here:

• będzie padać = it will rain / it will be raining

This is a normal way to talk about future weather.

You may also encounter another future pattern with imperfective verbs, but będzie padać is a very standard form and a good one to learn first.

Because padać is the normal Polish verb for things that fall from the sky, especially:

• deszcz pada = it is raining
• śnieg pada = it is snowing

So:

• będzie padać = it will rain / it will be raining

Polish does not use a dummy subject like English it. The verb alone is enough.

Because Polish is talking about a specific future situation: if it rains again tomorrow.

In Polish, after jeśli, you can absolutely use a future form when the condition is in the future:

• jeśli jutro będzie padać... = if it rains tomorrow...

That is perfectly normal.

Compare:

• Jeśli pada, zostaję w domu. = If it’s raining, I stay home.
  This sounds more like a general rule or present situation.
• Jeśli jutro będzie padać, zostanę w domu. = If it rains tomorrow, I’ll stay home.
  This is about a future event.

So the future in the if-clause is not a problem in Polish.

Znowu means again.

Here:

• jutro znowu będzie padać = tomorrow it will rain again

Its position is fairly flexible, but it is usually placed near the verb or near the part of the sentence it modifies.

For example:

• Jutro znowu będzie padać.
• Znowu będzie jutro padać.
  Grammatically possible, but less natural in ordinary speech.
• Jeśli jutro będzie znowu padać...
  Also possible.

The version in your sentence sounds natural and neutral.

Because in Polish, a subordinate clause introduced by words like jeśli is normally separated by a comma.

So:

• Czy masz zamiar zostać w domu, jeśli jutro znowu będzie padać?

That comma is standard Polish punctuation.

English often does not use a comma when the if-clause comes second, but Polish does.

Yes. Polish word order is more flexible than English, although not completely free.

For example, you could also say:

• Jeśli jutro znowu będzie padać, czy masz zamiar zostać w domu?

This version puts the condition first and may sound slightly more structured or emphatic.

The original version:

• Czy masz zamiar zostać w domu, jeśli jutro znowu będzie padać?

is very natural and neutral.

So word order can change, but the original sentence is perfectly standard.

It is basically neutral standard Polish.

Nothing in it is especially formal or especially casual:

• czy is standard
• masz zamiar is normal everyday Polish
• jeśli is neutral
• będzie padać is standard

In very casual speech, someone might simplify it a little:

• Zostajesz jutro w domu, jeśli znowu będzie padać?
• Masz zamiar zostać jutro w domu, jeśli znowu będzie padać?

But your original sentence is completely natural and correct.

A more direct version would remove the idea of intention and ask more simply about the future action:

• Czy zostaniesz w domu, jeśli jutro znowu będzie padać?

This means:

• Will you stay at home if it rains again tomorrow?

So the difference is:

• Czy masz zamiar zostać w domu...? = asks about your plan/intention
• Czy zostaniesz w domu...? = asks more directly what you will do

Both are correct, but they are not exactly the same in tone.
