Ne želim izaći iz kuće sve dok se ne umijem i ne obučem.

After verbs like željeti (to want), Croatian usually uses the infinitive when the subject is the same in both parts.

• Ne želim izaći = I don’t want to go out / leave
• literally: I don’t want to leave

This is the normal Croatian pattern. Using a full clause would usually be less natural here.

Because izaći is perfective: it means to go out / leave once, as a completed action.

• izaći = to go out, to leave, to step out once
• izlaziti = to be going out, to go out regularly, repeatedly, or in a more ongoing sense

In this sentence, the speaker means one specific completed act: they do not want to leave the house yet. So izaći is the natural choice.

The preposition iz (out of / from) takes the genitive case.

So:

• kuća = house
• iz kuće = out of the house / from the house

That is why you see kuće, not kuću or kuća.

Sve dok means until or right up until.

It is very similar to dok, but sve dok can sound a bit more emphatic, like:

• not until
• up until the point when

So the sentence means the speaker does not want to leave the house until those actions are completed.

This is one of the most common learner questions.

After dok / sve dok meaning until, Croatian normally uses ne with the verb:

• dok se ne umijem = until I wash up
• dok se ne obučem = until I get dressed

That ne is part of the Croatian until pattern. It does not translate as an English negative here.

A useful contrast is:

• dok se umivam = while I am washing
• dok se ne umijem = until I wash

So ne helps signal the endpoint.

Because Croatian often uses the present tense after time words like dok, kad, čim, even when the meaning is future.

Also, umijem and obučem here are perfective present forms. Perfective present in Croatian often refers to a future completed action:

• kad dođem = when I come
• dok se ne obučem = until I get dressed

So these are present-tense forms with future meaning, which is normal in Croatian.

Umiti se usually means to wash oneself, especially to wash one’s face / wash up.

In many contexts, English would translate it as:

• wash up
• wash my face
• sometimes simply wash

It usually does not mean taking a full shower or bath. So this sentence suggests something like washing up before going out.

Because obući se is the perfective verb: to get dressed, to finish dressing.

• obući se = get dressed, put clothes on completely
• oblačiti se = get dressed, be dressing, dress oneself in a more ongoing or habitual sense

Since the sentence is about waiting until the action is completed, obući se fits better.

It looks the same, but here it is a different verb form.

• umijem can be from umjeti = I know how to
• but se umijem here is from umiti se = to wash oneself

The reflexive se makes it clear:

• umijem plivati = I know how to swim
• umijem se = I wash up / I wash myself (in this kind of form)

So in this sentence, it definitely comes from umiti se.

Because se is a clitic: a short unstressed word that has special placement rules in Croatian.

In a clause like this, se tends to come near the beginning of the clause, after the conjunction phrase, while ne stays directly with the verb:

• sve dok se ne umijem

So the structure is not random. Croatian clitics often appear in an early position in the clause.

Because one se can be shared by both coordinated verbs:

• se ne umijem i ne obučem
• understood as: se ne umijem i (se) ne obučem

In English terms, it is like the reflexive idea carries over to both verbs. Croatian often avoids repeating the same clitic if it clearly belongs to both parts.

Because both verbs belong to the until structure, so repeating ne is the clearest and most natural standard wording:

• dok se ne umijem i ne obučem

This shows that both actions are required before the speaker will leave.

You may sometimes hear less careful speech where the second ne is omitted, but repeating it is the safest and most standard choice.

Yes. Croatian word order is fairly flexible, especially for emphasis.

For example, you could also say:

• Sve dok se ne umijem i ne obučem, ne želim izaći iz kuće.

That means the same thing, but it puts the until part first for emphasis.

What usually matters most is keeping the clitics and verb forms in natural Croatian positions.
