Pažljivo slušaj moju sestru.

Pažljivo means carefully.

It is an adverb, so it describes how the action is done. In this sentence, it tells you how to listen.

• pažljiv = careful, attentive (adjective)
• pažljivo = carefully, attentively (adverb)

So:

• Pažljivo slušaj = Listen carefully

Slušati is the infinitive, meaning to listen.

Slušaj is the imperative form, used to give a command or instruction to one person:

• slušati = to listen
• slušaj = listen!

So the sentence is giving an instruction: Listen carefully to my sister.

Slušaj is the 2nd person singular imperative.

That means it is used when speaking to one person informally, like English Listen!

Compare:

• slušaj! = listen! (to one person, informal)
• slušajte! = listen! (to more than one person, or one person formally)

So if you were speaking politely or to several people, you would say:

• Pažljivo slušajte moju sestru.

Because slušati takes a direct object, and the direct object here is in the accusative case.

The basic form is:

• moja sestra = my sister (nominative)

But after slušati, it changes to the accusative:

• moju sestru = my sister (accusative)

So:

• moja sestra = my sister is...
• slušaj moju sestru = listen to my sister

This is a very common pattern in Serbian.

Because moju and sestru belong together, and Serbian words often agree in gender, number, and case.

Here:

• sestra is a feminine singular noun
• moju is the matching form of moja in the accusative singular feminine
• sestru is also accusative singular feminine

So both words change to match the grammar of the sentence.

Pattern:

• moja sestra → nominative
• moju sestru → accusative

Yes. In Serbian, slušati usually takes a direct object without a preposition.

English says:

• listen to my sister

But Serbian says more literally:

• listen my sister

So:

• slušati nekoga/nešto = to listen to someone/something

That is why there is no separate word corresponding to English to in this sentence.

This is a very common learner question.

• slušati = to listen (active, intentional)
• čuti = to hear (perceive sound)

So in this sentence, slušaj is correct because the speaker is telling someone to pay attention and listen.

Examples:

• Slušam muziku. = I am listening to music.
• Čujem muziku. = I hear music.

So Pažljivo slušaj moju sestru means you should actively pay attention to what the sister is saying.

Yes, Serbian word order is more flexible than English, but this version is very natural.

This order is straightforward:

• Pažljivo = carefully
• slušaj = listen
• moju sestru = my sister

You may also hear other orders for emphasis, for example:

• Slušaj pažljivo moju sestru.
• Moju sestru pažljivo slušaj.

But Pažljivo slušaj moju sestru is a normal, clear way to say it.

Sestru is pronounced roughly like SEH-stru.

A few notes:

• e is like e in met
• str is pronounced as a consonant cluster, without extra vowels
• the final u is like oo in food, but shorter and purer

So moju sestru is roughly:

• MO-yoo SEH-stru

Also, Serbian pronunciation is usually quite regular compared with English spelling.

By itself, it sounds like a direct instruction. Whether it feels harsh depends on tone and situation.

It can be:

• neutral: a teacher, parent, or friend telling someone to pay attention
• firm: if said sharply
• helpful: if said kindly

If you want to soften it, Serbian can add words such as:

• Molim te, pažljivo slušaj moju sestru. = Please listen carefully to my sister.

So the basic sentence is not automatically rude, but it is definitely a command.

Not usually in the same way. Slušati and poslušati are related but not identical.

• slušati = to listen, to be listening
• poslušati can mean to listen to / obey / hear someone out, often with a more completed or one-time sense

In many everyday situations, Pažljivo slušaj moju sestru is the most natural way to say Listen carefully to my sister.

If you use poslušaj, the meaning may shift depending on context, sometimes closer to:

• Listen to my sister for a moment
• Do what my sister says
• Hear my sister out

So for a basic command about paying attention, slušaj is the safer choice.
