Molim vas, ispravite treći redak i upišite točan odgovor u desnu rubriku.

Here Molim vas means please.

Literally, molim means I ask / I beg, and vas means you. Together, it is a polite way to address:

• one person formally
• or more than one person

So this sentence is giving an instruction politely, not talking to a close friend in an informal way.

Because Molim vas is being used as an introductory polite phrase, like Please, ... in English.

In this sentence, it is separate from the main command:

• Molim vas,
• ispravite... i upišite...

So the comma helps show that Molim vas is not the main action of the sentence, but a polite marker.

The ending -te marks the imperative for:

• you plural
• or formal you singular

So both verbs are commands addressed politely to one person, or to several people.

Here:

• ispravite = correct
• upišite = write in / enter

If you were speaking informally to one person, the forms would be:

• ispravi
• upiši

These are perfective verbs, which is very common in instructions when the speaker wants the action to be completed.

• ispraviti = to correct, to make right
• upisati = to write in, enter

So the sentence is not describing an ongoing process. It is telling someone to perform two complete actions:

1. correct the third line
2. enter the correct answer in the right column

In instructions, perfective imperatives often sound very natural.

Treći redak is the direct object of ispravite, so it is in the accusative case.

But it looks the same as the nominative because:

• redak is a masculine inanimate noun
• masculine inanimate nouns often have the same form in nominative and accusative singular
• the adjective agrees with it, so treći also stays the same

So:

• nominative: treći redak
• accusative: treći redak

Even though the form is the same, the function is different.

For the same reason.

Točan odgovor is the direct object of upišite, so it is also in the accusative. But:

• odgovor is masculine singular inanimate
• in that pattern, accusative = nominative

So:

• nominative: točan odgovor
• accusative: točan odgovor

A feminine example would show the case more clearly:

• nominative: točna riječ
• accusative: točnu riječ

Because Croatian uses different cases after u depending on meaning:

• u + accusative = motion toward / into something
• u + locative = location inside something

Here the idea is enter the answer into the right column, so there is movement toward a destination. That is why Croatian uses the accusative:

• u desnu rubriku

If you were only describing where something already is, you would use locative:

• u desnoj rubrici = in the right column

Because desnu has to agree with rubriku.

Rubrika is:

• feminine
• singular
• accusative here

So the adjective must match it:

• nominative: desna rubrika
• accusative: desnu rubriku

This is standard adjective-noun agreement in Croatian.

In this sentence:

• redak = line of text
• rubrika = column, box, or section on a form, worksheet, or table

So treći redak is the third line, and desna rubrika is the right-hand column/box where the answer should be written.

Because Croatian often leaves out subject pronouns when they are already clear from the verb form.

Here, the ending -te already tells you that the command is addressed to:

• you plural
• or you formal singular

So there is no need to add vi. Croatian normally prefers to omit it unless there is special emphasis.

Yes, Croatian word order is more flexible than English word order, but the version here is the most neutral and natural for an instruction.

This order is clear and practical:

• Molim vas, ispravite treći redak
• i upišite točan odgovor u desnu rubriku

You can move parts around for emphasis, but not every alternative sounds equally natural. In ordinary instructions, the original order is a very good standard choice.

A rough pronunciation guide is:

MO-leem vas, ees-PRAH-vee-teh TREH-chee REH-dak ee OO-pee-shee-teh TOH-chan od-GOH-vor oo DEHS-noo ROO-bree-koo

A couple of useful sound notes:

• č in točan is like the ch in church
• ć in treći is softer than č
• š in upišite is like sh in shoe

Croatian spelling is generally quite regular, so once you learn the letter sounds, pronunciation becomes much easier.
