Azi curierul lasă pachetul jos, lângă ușă.

Because Romanian usually puts the definite article at the end of the noun, not before it like English the.

• curier = courier

• curierul = the courier

• pachet = package
• pachetul = the package

In this sentence:

• curierul = the courier
• pachetul = the package

A useful extra detail: curier is masculine, and pachet is neuter. In the singular, neuter nouns use the same article pattern as masculine nouns, which is why both can take -ul.

Lasă is the 3rd person singular present form of a lăsa.

So:

• a lăsa = to leave, to let, to put down
• el/ea lasă = he/she leaves, he/she puts down

Here the subject is curierul, so lasă means the courier leaves / puts down.

It can suggest both, depending on context.

In this sentence, because of jos, lângă ușă (down, near the door), lasă most naturally means something like:

• puts down
• sets down
• or leaves

So the idea is not just that the courier departs, but that he places the package down and leaves it there.

Romanian word order is fairly flexible, and putting Azi first gives today a little prominence.

So:

• Azi curierul lasă pachetul jos, lângă ușă.

feels like:

• Today, the courier leaves/puts the package down near the door.

Starting with the time expression is very common in Romanian, especially when setting the scene.

Yes. Both mean today.

• azi = today
• astăzi = today

The difference is mainly style:

• azi is shorter and very common in everyday speech
• astăzi can sound a bit fuller or slightly more formal, though it is still normal speech

So this sentence could also be:

• Astăzi curierul lasă pachetul jos, lângă ușă.

Jos means down or downwards.

Here it tells you that the package is being placed down, not just left in some vague way. In context, it suggests:

• on the floor
• down near the door
• set down by the door

So lasă pachetul jos is stronger than just lasă pachetul. It makes the physical action clearer.

This is a very natural question, because English would normally say near the door.

In Romanian, both forms can exist, but they feel slightly different:

• lângă ușă = near/by the door, often more general as a location
• lângă ușa = near the specific door

In everyday Romanian, a bare noun after a preposition can sound perfectly natural in location expressions, especially when the exact identity of the object is less important than the place itself.

So in this sentence, lângă ușă sounds like a natural locational phrase: by the door / near the doorway area.

Because pachetul is an inanimate direct object.

Romanian often uses pe with animate, especially human, definite direct objects, for example:

• Văd băiatul / Îl văd pe băiat
• Ascult pe profesor is regional/nonstandard in some contexts; standard Romanian typically uses pe with specific animate/human objects in many common constructions

But with an inanimate noun like pachetul, Romanian normally does not use pe:

• Curierul lasă pachetul = correct
• Curierul lasă pe pachetul = not correct here

The important special letters here are:

• ă
• â
• ș

Roughly:

• ă = a schwa sound, like the a in about
• â = a sound English does not really have; it is central and close. You may hear it described approximately, but there is no perfect English match.
• ș = sh

Very rough pronunciation guides:

• lasă ≈ LA-suh
• lângă ≈ LUHN-guh (very approximate; the â is not a true English sound)
• ușă ≈ OO-shuh

And:

• azi ≈ AH-zee

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

Not always. In a sentence like this, the comma is often more about rhythm or a slight pause than strict necessity.

You may see both:

• Azi curierul lasă pachetul jos, lângă ușă.
• Azi curierul lasă pachetul jos lângă ușă.

Both can be understood. The version with the comma slightly separates the final location phrase for clarity or style.

Yes. Romanian allows more movement than English, although some orders sound more natural than others.

For example:

• Azi curierul lasă pachetul jos, lângă ușă.
  Neutral, with emphasis on today

• Curierul lasă pachetul jos, lângă ușă, azi.
  Possible, but now azi is more strongly highlighted at the end

• Curierul azi lasă pachetul jos, lângă ușă.
  Possible, though less neutral in everyday speech

The original version is very natural because it starts with the time expression and then gives the rest of the information.

After lângă, Romanian uses the form associated with the accusative.

In practice, for many nouns, the accusative looks the same as the nominative, especially in the indefinite singular. So:

• ușă can be nominative or accusative in form
• after lângă, its role is prepositional/accusative

So you do not need a special new ending here; the form stays ușă.

Yes, ușă is a feminine noun.

A helpful clue is its singular ending:

• many feminine Romanian nouns end in -ă
• ușă = door
• definite singular: ușa = the door

So:

• o ușă = a door
• ușa = the door

This is why, if the definite form were used after lângă, it would be lângă ușa, not lângă ușul or anything similar.
