Vorbesc cu vecina de la etajul doi de mult timp.

Romanian often drops the subject pronoun when the verb ending already makes the subject clear.

• vorbesc = I speak / I am speaking
• The ending -esc here shows 1st person singular.

So Vorbesc by itself already means I speak or I am speaking, and you do not need eu unless you want emphasis:

• Eu vorbesc... = I am the one speaking / I speak...

Vecina means the female neighbor.

Romanian distinguishes grammatical gender, and this noun is feminine:

• vecin = neighbor (male or unspecified in some contexts)
• vecina = female neighbor

The ending -a here also includes the definite article, so:

• vecină = a female neighbor
• vecina = the female neighbor

So cu vecina means with the female neighbor or more naturally to the female neighbor, depending on the meaning of a vorbi cu.

The verb a vorbi commonly takes cu, which literally means with:

• vorbesc cu Maria = I speak with / talk to Maria

This is very natural Romanian. Even though English often prefers talk to someone, Romanian uses cu in this structure.

So:

• Vorbesc cu vecina = I talk to the neighbor / I am speaking with the neighbor

It means from the second floor.

Breakdown:

• de la = from
• etajul = the floor
• doi = two

Together:

• vecina de la etajul doi = the neighbor from the second floor

In Romanian, this phrase identifies which neighbor you mean.

Because Romanian often attaches the definite article to the end of the noun.

• etaj = floor
• etajul = the floor

This is called the enclitic definite article. Instead of a separate word like English the, Romanian usually adds it to the noun itself.

So:

• de la etaj = from a floor / from floor
• de la etajul doi = from the second floor

Romanian can express ordinal ideas like second floor in a more compact way after certain nouns.

So:

• etajul doi = floor two = the second floor

This is very common in addresses and building floors.

A more explicitly ordinal form would be:

• etajul al doilea = the second floor

Both are possible, but etajul doi is very natural in everyday speech.

De mult timp means for a long time.

Breakdown:

• de = for / since, in time expressions like this
• mult = much / long
• timp = time

So the whole phrase expresses duration:

• de mult timp = for a long time

It tells you that the action has been going on for quite a while.

This is a very important point. Romanian often uses the present tense for actions that started in the past and still continue now.

So:

• Vorbesc ... de mult timp literally looks like I speak ... for a long time
• but in natural English it is often translated as I have been talking ... for a long time

This is normal Romanian usage. The present tense can cover an ongoing action that began earlier and continues into the present.

Potentially all of those, depending on context.

In this sentence, because of de mult timp, the most natural English translation is often:

• I have been talking to the neighbor from the second floor for a long time

Without more context, Vorbesc itself is simply present tense, but the time phrase pushes the meaning toward an ongoing situation.

So Romanian present tense can map to several English forms:

• I speak
• I am speaking
• I have been speaking

Context decides.

It describes vecina.

So the structure is:

• [Vorbesc] [cu vecina de la etajul doi] [de mult timp].

This means:

• I have been talking [to the neighbor from the second floor] [for a long time].

It does not mean that the speaking is happening from the second floor. The phrase identifies which neighbor.

Yes, Romanian word order is fairly flexible, though some orders sound more neutral than others.

The given sentence is natural:

• Vorbesc cu vecina de la etajul doi de mult timp.

You might also hear:

• De mult timp vorbesc cu vecina de la etajul doi.

That puts more emphasis on for a long time.

Even though word order can change, the original version is a very normal, neutral sentence.

Yes. After cu, Romanian normally uses the regular noun form here, not a special dative form.

So:

• cu vecina = with / to the female neighbor

Romanian cases do exist, but after a preposition like cu, you usually get the expected prepositional form, not something like English learners might expect from a highly inflected language.

In this sentence, vecina is exactly what you should expect after cu.

A Romanian speaker would understand it as something like:

• I’ve been talking to the neighbor from the second floor for a long time
• or I’ve known / been on speaking terms with the neighbor from the second floor for a long time, depending on context

The core idea is:

1. I
2. talk to / speak with
3. the female neighbor from the second floor
4. for a long time

So it is a straightforward everyday sentence, but it also shows several useful Romanian patterns:

• dropped subject pronoun
• definite article attached to the noun
• cu after a vorbi
• present tense used for an action continuing up to now
