Da li mogu da uzmem ovu košulju i da platim sutra?

Da li is a very common way to turn a statement into a yes/no question in Serbian.

So:

• Mogu da uzmem ovu košulju... = I can take this shirt...
• Da li mogu da uzmem ovu košulju...? = Can I take this shirt...?

It does not have a neat one-word English equivalent. Think of it as a question marker.

A very common alternative is:

• Mogu li da uzmem ovu košulju i da platim sutra?

That means the same thing and is often felt to be a bit shorter or smoother.

Mogu is the 1st person singular present form of moći (to be able / can).

So here it means I can / may I.

This verb is a little irregular, which is why learners often notice it. Its present tense goes like this:

• ja mogu = I can
• ti možeš = you can
• on/ona/ono može = he/she/it can
• mi možemo = we can
• vi možete = you can (plural/formal)
• oni/one/ona mogu = they can

Notice that mogu is used for both I can and they can. The subject or context tells you which one is meant.

Because Serbian very often uses da + present tense where English uses an infinitive.

So English says:

• Can I take...
• Can I pay...

But Serbian often says literally more like:

• Can I that-I-take...
• Can I that-I-pay...

That sounds strange in English, but it is normal Serbian grammar.

After modal verbs like moći, the da + present structure is extremely common:

• Mogu da uzmem
• Mogu da platim

You may also hear infinitives in some contexts or styles, but for Serbian, da + present is one of the most important patterns to learn.

Because after da, these present-tense forms do not always mean right now.

In this kind of sentence, they usually express:

• an intended action
• a possible action
• a future action

So:

• da uzmem = to take / that I take
• da platim = to pay / that I pay

Even though the forms are present tense, the meaning depends on the whole sentence. Since the speaker is asking for permission or possibility, the actions are naturally understood as happening after now.

Because ovu košulju is in the accusative case, which is used here for the direct object of uzmem.

The basic dictionary form is:

• ova košulja = this shirt (nominative)

But after a verb like uzeti (to take), you need the direct object form:

• ovu košulju = this shirt (accusative)

Both the adjective/pronoun ova and the noun košulja change:

• ova košulja → nominative
• ovu košulju → accusative

This is a very typical Serbian pattern.

Because it is a feminine singular noun being used as a direct object.

For many feminine nouns ending in -a, the accusative singular ends in -u:

• žena → ženu
• knjiga → knjigu
• košulja → košulju

So košulju is simply the correct object form after uzmem.

Because Serbian often repeats da when two verbs are coordinated.

So:

• da uzmem ... i da platim ...

This keeps the structure clear and parallel:

• Can I take ... and pay ...

Repeating da is very natural and standard here. It shows that both verbs depend on mogu.

You can think of the structure as:

• mogu [da uzmem...] i [da platim...]

For a learner, repeating da is the safest and most natural choice.

Because the speaker is talking about one complete action in each case:

• uzmem = take (one completed act)
• platim = pay (one completed act)

These come from perfective verbs:

• uzeti → uzmem
• platiti → platim

Perfective is natural here because the idea is:

• take the shirt once
• pay once, tomorrow

If you used imperfective verbs, the meaning would shift toward something more ongoing, repeated, or less bounded, which does not fit as well here.

This is a very important Slavic aspect distinction:

• perfective = a completed whole
• imperfective = ongoing, repeated, habitual, or uncompleted

Yes. Both are correct and common.

You can say:

• Da li mogu da uzmem ovu košulju i da platim sutra?
• Mogu li da uzmem ovu košulju i da platim sutra?

The meaning is the same.

Very roughly:

• Da li mogu... = neutral, standard, very common
• Mogu li... = also very common, often a bit shorter and elegant
• Je l' mogu... = more conversational/colloquial

So yes, Mogu li... is an excellent alternative.

Because that is a very natural, neutral place for it.

Here sutra modifies platim, so the sentence ends with the time expression:

• ... i da platim sutra

Serbian word order is fairly flexible, so you could move sutra for emphasis, for example:

• Da li mogu da uzmem ovu košulju i da sutra platim?

But the original version sounds very normal and unmarked. Putting sutra at the end is a simple, natural choice.

Yes, it is grammatical and natural.

It sounds like a polite request asking whether it is possible to:

• take the shirt now
• pay tomorrow

The politeness mainly comes from:

• the question form
• mogu (can/may I)
• the overall indirect phrasing

If you want, Serbian can also sound a bit softer with intonation or added polite words such as:

• molim vas = please
• izvinite = excuse me

For example:

• Da li mogu, molim vas, da uzmem ovu košulju i da platim sutra?

But the original sentence is already polite enough on its own.
