المكتب في الدور الاول، والاسانسير جنب الباب.

Because Arabic usually drops the present-tense verb to be.

So:

• المكتب في الدور الأول literally looks like the office in/on the first floor
• but it means The office is on the first floor

And:

• الاسانسير جنب الباب literally looks like the elevator next to the door
• but it means The elevator is next to the door

This is very normal in both Egyptian Arabic and Standard Arabic. If you wanted was, then you would usually need a verb such as كان.

Arabic في is broader than English in. Depending on context, it can correspond to in, at, or on.

So with floors, Arabic says:

• في الدور الأول

Even though the most natural English translation is:

• on the first floor

So this is not a mistake or a weird choice—it's just how Arabic expresses location.

الدور means floor or storey of a building, and الأول means first.

So الدور الأول means the first floor.

A useful cultural note: in Egypt, الدور الأرضي is the ground floor, and الدور الأول is usually the floor above it. That matches British-style numbering more than American usage. But building conventions can still vary, so context matters.

Yes. مكتب can mean:

• office
• desk

Context tells you which one is meant.

In this sentence, because we are talking about a floor and an elevator, المكتب clearly means the office, not the desk.

جنب means next to, beside, or by.

So:

• جنب الباب = next to the door

In Egyptian Arabic, جنب is very common in everyday speech. A more formal or Standard Arabic equivalent would be بجانب.

You may also notice that جنب literally has the idea of side, so the basic image is at the side of the door.

It is a very common borrowed word in Egyptian Arabic. It comes from French ascenseur.

In everyday Egyptian speech, الاسانسير is completely normal and very common.

The more formal/Standard Arabic word is:

• المصعد = the elevator

So in Egypt:

• الاسانسير sounds natural and conversational
• المصعد sounds more formal, official, or Standard Arabic

ال is the Arabic definite article, equivalent to the.

Here you have:

• المكتب = the office
• الدور الأول = the first floor
• الاسانسير = the elevator
• الباب = the door

Arabic often uses definiteness when the speaker is talking about something identifiable from context. In a building, for example, the office, the elevator, and the door can all be understood as specific things.

Also, in الدور الأول, the adjective/ordinal الأول is definite because it matches the definite noun الدور.

A natural approximation is:

el-maktab fi d-dawr il-awwal, wil-asanseer gamb il-bab

A few pronunciation notes:

• المكتب → el-maktab
• الدور is written with ال, but the l sound assimilates because د is a sun letter, so you hear something like ed-dawr or id-dawr
• الأول → il-awwal
• والاسانسير often sounds like wil-asanseer
• الباب keeps the l sound of the article, because ب is a moon letter: il-bab

So learners often read it too literally at first, but the spoken form is smoother than the spelling suggests.

Because in Arabic script, و meaning and is written as a prefix attached to the following word.

So:

• والاسانسير = و + الاسانسير
• literally: and + the elevator

This is completely standard Arabic spelling. The same thing happens all the time with other short particles and prefixes.

So when you read والاسانسير, you should mentally split it as:

• و = and
• الاسانسير = the elevator

This order is very natural:

• المكتب في الدور الأول، والاسانسير جنب الباب

It starts with the thing being talked about, then gives its location. That is a very common Arabic pattern.

You could change the order for emphasis, for example:

• في الدور الأول المكتب
• جنب الباب الاسانسير

But those are less neutral and would usually sound marked or context-driven. For a straightforward statement, the original order is the most natural choice.
