Semnezi aici, iar apoi primești documentul.

Semnezi is the 2nd person singular form of a semna (to sign), so it is used when speaking to one person informally: you sign.

Semnați would be used for:

• you all sign (plural), or
• you sign in a formal/polite way to one person.

So:

• Semnezi aici = You sign here (to one person, informal)
• Semnați aici = You sign here (formal or plural)

Romanian often leaves out subject pronouns because the verb ending already shows who is doing the action.

In semnezi, the ending -ezi tells you it means you (singular). In primești, the ending -ești also tells you it means you (singular).

So Romanian does not need tu unless the speaker wants to add emphasis or contrast.

Compare:

• Semnezi aici = You sign here
• Tu semnezi aici = You sign here (more emphasis)

Romanian often uses the present tense to give instructions, directions, or describe the next step in a process.

So Semnezi aici, iar apoi primești documentul literally looks like:

• You sign here, and then you receive the document

But functionally it means something like:

• Sign here, and then you get the document
• You sign here, then you receive the document

This is very natural in procedural language, such as at an office, counter, or reception desk.

For the first verb, yes:

• Semnează aici = Sign here

That is a direct command.

But the second part is less naturally imperative, because receiving the document is not really something the listener actively commands themself to do. That is why the present-tense instruction style sounds more natural in this context:

• Semnezi aici, iar apoi primești documentul.

It presents the steps in a process rather than giving two sharp commands.

Here iar works as a connector meaning something like:

• and then
• and after that

In many other contexts, iar can also mean:

• while
• whereas
• but/on the other hand

So it is a flexible word, and its meaning depends on context.

In iar apoi, it helps connect the two actions smoothly:

• Semnezi aici, iar apoi... = You sign here, and then...

Yes, you could simply say:

• Semnezi aici, apoi primești documentul.

That is completely correct.

Adding iar makes the transition a little smoother or slightly more structured:

• iar apoi = and then / and after that

So:

• apoi = simpler
• iar apoi = a bit more connected or formal-sounding

Primești is the 2nd person singular present form of a primi (to receive).

The present forms are:

• eu primesc = I receive
• tu primești = you receive
• el/ea primește = he/she receives
• noi primim = we receive
• voi primiți = you all receive
• ei/ele primesc = they receive

So in the sentence:

• primești documentul = you receive the document

A learner may notice that the verb stem changes a little:

• dictionary form: primi
• present form: primești

That is normal.

Because documentul means the document.

Romanian usually puts the definite article at the end of the noun instead of using a separate word like English the.

So:

• document = document / a document
• documentul = the document

This is one of the most important features of Romanian grammar.

Other examples:

• băiat = boy
• băiatul = the boy
• carte = book
• cartea = the book

Because documentul is the direct object of primești.

In English, we say:

• receive the document

Romanian works the same way here:

• primești documentul

No extra preposition is needed.

A learner might wonder about pe, but pe is not used here. Romanian typically uses pe with certain direct objects, especially people or specific animate beings:

• Văd băiatul = I see the boy
• Îl văd pe băiat = I see the boy

But with an inanimate noun like documentul, you normally just say:

• primești documentul

As written, it sounds informal or at least non-polite singular, because it uses:

• semnezi
• primești

If you wanted to address someone politely, you would usually say:

• Semnați aici, iar apoi primiți documentul.

That would be appropriate in customer service, official situations, or when speaking respectfully to one person.

So the choice between semnezi / primești and semnați / primiți depends on the relationship and level of formality.

The sentence as given is very natural:

• Semnezi aici, iar apoi primești documentul.

Romanian does allow some flexibility in word order, but not every version sounds equally natural.

For example:

• Aici semnezi, iar apoi primești documentul.
  This puts more emphasis on here.
• Semnezi aici și apoi primești documentul.
  Also very natural.

So the original order is normal and clear, but Romanian can move words around a bit for emphasis.

Primești is pronounced roughly like pree-MESH-tee.

A few key points:

• ș sounds like English sh
• ești sounds roughly like eshtee
• the stress is on the middle syllable: pri-MEȘTI

So:

• primești ≈ pree-MESH-tee

Also:

• semnezi ≈ sem-NEHZ
• aici ≈ ah-YEECH

These are only approximations, but they can help at the start.
