Czy mamy jutro przynieść oryginały, czy wystarczą dobre kopie?

They do two slightly different jobs.

• The first czy introduces the whole yes/no question.
• The second czy means or and introduces the alternative.

So the pattern czy X, czy Y? is a very natural Polish way to ask X or Y? in a full sentence.

Mamy + infinitive often means are we supposed to..., are we meant to..., or do we have to....

So mamy przynieść is not just the literal we have bring. It expresses an expected action, often based on instructions, plans, or requirements.

It is slightly different in tone from musimy przynieść, which sounds more like a stronger obligation: we must / we have to bring.

Because przynieść is perfective.

In this sentence, the speaker is asking about one specific completed action in the future: bringing something tomorrow, once. Perfective verbs are the normal choice for that.

• przynieść = bring once, as a completed act
• przynosić = be bringing / bring repeatedly / bring in a general or ongoing sense

So jutro przynieść sounds natural because it refers to one concrete occasion.

Because wystarczyć is also a perfective verb.

In Polish, perfective verbs do not have a true present tense. Their present-looking forms actually refer to the future.

So:

• wystarczą = will be enough
• imperfective wystarczają = are enough / are sufficient

That is why czy wystarczą dobre kopie? means or will good copies be enough?

It is the accusative plural, because it is the direct object of przynieść.

You bring something, so that something is the object.

Here the noun is oryginał. In the plural, for masculine inanimate nouns, the nominative plural and accusative plural often look the same:

• nominative plural: oryginały
• accusative plural: oryginały

So even though the form looks like nominative, its role here is accusative.

No. In wystarczą dobre kopie, kopie is the subject.

With wystarczyć, the thing that is enough is the grammatical subject:

• Dobre kopie wystarczą.
• Good copies will be enough.

That is why the verb is plural: wystarczą agrees with kopie.

Because the adjective has to agree with the noun.

Kopie is plural and belongs to the non-masculine-personal group, so the adjective takes the form dobre.

Compare:

• singular: dobra kopia
• plural: dobre kopie

So dobre kopie simply shows normal adjective-noun agreement.

Yes, and the sentence would still be natural, but the nuance changes.

• mamy przynieść = are we supposed to bring / are we meant to bring
• musimy przynieść = do we have to bring / must we bring

Mamy often suggests checking instructions or arrangements. Musimy sounds more like asking about strict necessity.

Yes. Polish word order is flexible.

In this sentence, Czy mamy jutro przynieść... is a neutral, natural order. But you could also say:

• Czy jutro mamy przynieść oryginały...?
• Czy mamy przynieść oryginały jutro...?

These versions are also possible, but they may shift the emphasis slightly:

• earlier jutro = more focus on when
• later jutro = more focus on the action/object first

The basic meaning stays the same.

Both are possible.

After czy, Polish often allows a verb-first order quite naturally, especially in questions:

• czy wystarczą dobre kopie?
• czy dobre kopie wystarczą?

The version in your sentence sounds very normal. The difference is mostly about rhythm and emphasis, not basic meaning.

Because the sentence contains two coordinated alternatives:

• czy mamy jutro przynieść oryginały
• czy wystarczą dobre kopie

In Polish, a comma is normally used to separate these parts in a structure like czy..., czy...?

So the comma is standard punctuation here.

Because Polish does not have articles like English a/an and the.

That means words like oryginały and kopie can be understood as:

• the originals
• originals
• good copies
• some good copies

The exact interpretation comes from context, not from an article.
