Molim te, pročitaj poruku još jednom.

Molim te is a very common way to say please when speaking to one person informally.

Literally:

• molim = I ask / I beg / please
• te = you (informal singular, in the accusative)

So the whole phrase is literally something like I ask you, but in normal usage it simply functions as please.

It is informal singular.

You use te when speaking to:

• one friend
• one child
• one family member
• someone you address with ti

The formal or plural version is:

Molim Vas, pročitajte poruku još jednom.

Here:

• Vas = formal you or plural you
• pročitajte = formal/plural imperative

Because Molim te is treated like an introductory polite expression, separate from the main command.

So Serbian normally writes:

Molim te, pročitaj poruku još jednom.

The main action starts with pročitaj.

This is similar to English punctuation in sentences like:

• Please, read the message again.

Although English often omits the comma, Serbian commonly keeps it in this kind of structure.

This is about aspect, which is very important in Serbian.

• čitati = to read (imperfective)
• pročitati = to read through / to finish reading (perfective)

The imperative pročitaj comes from pročitati and suggests:

• one complete action
• reading the message from start to finish
• doing it once more

That is exactly what fits this sentence.

Compare:

• Čitaj! = Read! / Keep reading!
• Pročitaj! = Read it through! / Finish reading it!

In requests for a single completed action, Serbian very often prefers the perfective imperative.

Because poruku is in the accusative case.

The noun poruka is feminine singular.

Its forms are:

• poruka = nominative
• poruku = accusative

Since it is the direct object of the verb pročitaj (read what?), Serbian uses the accusative:

• pročitaj poruku = read the message

This is a very common pattern:

• Imam knjigu. = I have a book.
• Pišem poruku. = I am writing a message.
• Pročitaj poruku. = Read the message.

Još jednom means once more, one more time, or again.

Literally:

• još = more / still / yet
• jednom = once / one time (instrumental form of jedan in this expression)

Together, još jednom is a very common expression meaning:

• again
• one more time

So:

• pročitaj poruku još jednom = read the message one more time

No, Serbian word order is fairly flexible, but the original sentence sounds very natural and neutral.

Molim te, pročitaj poruku još jednom.

This order gives:

1. polite opener
2. verb
3. object
4. expression of repetition

You may also hear variations, for example:

• Molim te, još jednom pročitaj poruku.
• Poruku pročitaj još jednom.

These are possible, but they can shift emphasis slightly. The original version is a very normal default choice.

A rough pronunciation guide:

• pročitaj ≈ pro-CHEE-tie
• još ≈ yosh

A few important letters:

• č sounds like ch in church, but a bit firmer
• j sounds like y in yes
• š sounds like sh in ship

So:

• pročitaj = pro + či + taj
• još jednom ≈ yosh YED-nom

English-style spellings are only approximations, but these should get you close.

No. Poruka can mean message in a broad sense.

Depending on context, it may refer to:

• a text message
• a written message
• a spoken message
• a general message or statement

So in this sentence, poruku could mean:

• a text on a phone
• a note
• an email message
• some other message already understood from context

Sometimes, but not usually in the same way.

Molim by itself can mean things like:

• please
• go ahead
• you’re welcome
• pardon?

But when making a direct request to someone informally, Molim te sounds much more natural and complete.

So for this sentence, Molim te, pročitaj poruku još jednom. is the better choice.
