نزلت من المترو عند المحطة اللي جنب العمارة الجديدة.

A natural pronunciation is:

nezelt men el-metro ʿand el-maḥaṭṭa elli ganb el-ʿamāra el-gedīda

A few notes:

• جديدة is pronounced gedīda in Egyptian, not jadīda
• اللي is often pronounced elli
• جنب is usually ganb in Egyptian speech

It can mean either in writing.

That is because short vowels are usually not written, so نزلت could be:

• nezelt = I got off
• nezlet = she got off

In real conversation, context usually makes it clear. If you want to remove ambiguity, you can add the subject:

• أنا نزلت = I got off
• هي نزلت = she got off

Because نزل من is the normal way to say get off / get out of / come down from something.

So:

• نزلت من المترو = literally I got down from the metro
• natural English meaning: I got off the metro

Arabic often uses a preposition where English does not.

Here عند means at, by, or near.

So:

• عند المحطة = at the station

In this sentence, it marks the place where the speaker got off.

It is slightly different from في:

• في المحطة = in the station
• عند المحطة = at/by the station

With transport stops or landmarks, عند is very common in Egyptian Arabic.

اللي is the Egyptian Arabic relative word meaning that, which, or who.

So:

• المحطة اللي جنب العمارة الجديدة = the station that is next to the new building

A very important point: in Egyptian Arabic, اللي does not change for gender or number. It is used for:

• masculine
• feminine
• singular
• plural
• people or things

That is much simpler than MSA, which has forms like الذي and التي.

Because Arabic normally does not use a present-tense is/are in sentences like this.

So:

• المحطة اللي جنب العمارة الجديدة literally looks like
• the station that next to the new building

But the meaning is:

• the station that is next to the new building

This is completely normal in both Egyptian Arabic and MSA.

جنب means next to, beside, or by the side of.

So:

• جنب العمارة الجديدة = next to the new building

It originally relates to the idea of side, but in everyday speech it works like a preposition.

You may also hear:

• بجانب = beside / next to
  But جنب is very common and natural in spoken Egyptian.

Because both the noun and the adjective are definite here.

• العمارة = the building
• الجديدة = the new

In Arabic, if the noun is definite, the adjective must also be definite.

So:

• عمارة جديدة = a new building
• العمارة الجديدة = the new building

This matching is very important in Arabic.

Because it describes العمارة, and عمارة is feminine.

Adjectives in Arabic agree with the noun they describe in:

• gender
• number
• definiteness

So:

• العمارة الجديدة = feminine noun + feminine adjective
• if it were masculine, you would get الجديد

Also notice the adjective comes after the noun in Arabic:

• العمارة الجديدة literally
• the building the-new

In Egyptian Arabic, عمارة often means a residential building or apartment block, not just any abstract building.

So depending on context, العمارة الجديدة could mean:

• the new building
• the new apartment building
• the new block

If you wanted a more general or formal word for building, you might hear مبنى, but عمارة is very common in everyday Egyptian speech.

Yes, but the original order is very natural:

نزلت من المترو عند المحطة اللي جنب العمارة الجديدة

This flows well because it gives:

1. the action
2. what you got off
3. where you got off

A different order might still be understood, but it can sound less smooth. For example:

• نزلت عند المحطة اللي جنب العمارة الجديدة من المترو

This is understandable, but the original version is more natural for everyday speech.

Not necessarily. محطة can be used for a station or stop in general, depending on context.

Examples:

• محطة مترو = metro station
• محطة قطر = train station
• محطة أتوبيس = bus stop/station

In this sentence, because you already have المترو, the meaning of المحطة is clearly the metro station.
