U uredu svaki dan primam puno poruka.

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

Here, primam means I receive or I am receiving, so the subject ja is understood automatically.

• primam = I receive
• primaš = you receive
• prima = he/she/it receives

You could say Ja u uredu svaki dan primam puno poruka, but that would sound more emphatic, like I receive a lot of messages.

Because u can take different cases depending on the meaning:

• u + locative = location, in / at
• u + accusative = motion toward something, into / to

So:

• U uredu = in the office → location
• Idem u ured = I’m going to the office → movement

In your sentence, the speaker is located in the office, so Croatian uses the locative: uredu.

Uredu is the locative singular of ured.

The noun is:

• nominative: ured = office
• locative: uredu = in the office after u

So u uredu literally means in office, with the correct Croatian case ending for location.

No, they are different.

• u uredu = in the office
• u redu = all right / okay / in order

They look and sound similar, so learners often confuse them.

Examples:

• Radim u uredu. = I work in the office.
• Sve je u redu. = Everything is fine.

So in your sentence, it is definitely u uredu, from ured meaning office.

Svaki dan means every day. This is a common time expression in Croatian.

Here, dan is in the accusative singular, used adverbially to express time. English does something similar with expressions like every day, where no preposition is needed.

Because dan is a masculine inanimate noun, its accusative singular looks the same as the nominative singular:

• nominative: dan
• accusative: dan

So even though the form does not change, the function is accusative.

Yes. Both are correct and both mean every day.

• svaki dan
• svakog dana

For many learners, svaki dan feels more straightforward and common in everyday speech. Svakog dana is also very natural, but can sound a little more stylistic or slightly more formal depending on context.

So you could say:

• U uredu svaki dan primam puno poruka.
• U uredu svakog dana primam puno poruka.

Both are good.

Because primam is the imperfective form, and it fits a repeated, habitual action like every day.

• primati → primam = imperfective, ongoing/repeated/habitual
• primiti → primim = perfective, completed action

Since the sentence describes something that happens regularly, primam is the natural choice:

• svaki dan primam = I receive every day

A perfective form like primim usually points to a completed event rather than a general routine.

It can mean either, depending on context.

Croatian present tense often covers both:

• I receive
• I am receiving

In this sentence, because of svaki dan (every day), the meaning is clearly habitual:

I receive a lot of messages every day in the office.

So here it is not really about one moment happening right now, but about a regular pattern.

Because after quantity words like puno (a lot of), Croatian normally uses the genitive.

So:

• puno = a lot of
• poruka here = of messages in the genitive plural

The noun poruka looks like this:

• singular nominative: poruka = message
• plural nominative: poruke = messages
• plural genitive: poruka = of messages

That is why the sentence has puno poruka.

In this sentence, puno means a lot of / many. It functions as a quantity word.

It does not behave exactly like a normal adjective here. The important thing for a learner is this:

• puno is followed by the genitive
• so you get puno poruka, puno vremena, puno ljudi

Examples:

• puno knjiga = a lot of books
• puno posla = a lot of work
• puno poruka = a lot of messages

Yes. Croatian word order is more flexible than English word order.

Your sentence is natural:

U uredu svaki dan primam puno poruka.

But these are also possible:

• Svaki dan u uredu primam puno poruka.
• Primam puno poruka u uredu svaki dan.
• Puno poruka primam u uredu svaki dan.

The core meaning stays similar, but the emphasis changes:

• U uredu... puts the location first
• Svaki dan... puts the time first
• Puno poruka... highlights the quantity

So Croatian word order is often about emphasis and information flow, not just grammar.
