الراوتر في المكتب.

A natural Egyptian-style pronunciation is er-router fil-maktab.

A few helpful notes:

• الراوتر is written with ال but pronounced er- here, because ر is a sun letter, so the l sound of the article blends into the r.
• في المكتب is often said smoothly as fil-maktab in connected speech.
• So the whole sentence flows like: er-router fil-maktab.

In Arabic, especially in the present tense, you usually do not say a separate word for is / am / are.

So:

• الراوتر في المكتب literally looks like the router in the office
• but it naturally means The router is in the office

This is completely normal in Egyptian Arabic.

الـ is the Arabic definite article, meaning the.

So:

• الراوتر = the router
• المكتب = the office or the desk, depending on context

In this sentence, both nouns are definite.

Because ر is one of the Arabic sun letters.

When الـ comes before a sun letter, the l sound is not pronounced clearly. Instead, the next consonant is emphasized or doubled.

So:

• written: الراوتر
• pronounced: er-router or ar-router, depending on style

This is the same pattern you see in many Arabic words beginning with sun letters.

في means in.

When speaking, Egyptians often connect words smoothly:

• في المكتب becomes something like fil-maktab

This does not change the meaning. It is just natural connected pronunciation:

• في = in
• المكتب = the office
• في المكتب = in the office

It can mean office, and in some contexts it can also mean desk.

Which meaning is intended depends on context. In your sentence, if the meaning shown is office, then that is the intended meaning here.

So learners should remember:

• مكتب can have more than one related meaning
• context tells you which one is right

It works in both, but the pronunciation is what makes it feel Egyptian.

For example:

• Egyptian-style pronunciation: er-router fil-maktab
• More formal/standard-style pronunciation: ar-rāwter fī al-maktab

The structure itself is very basic and widely understandable.

The pattern is:

• الراوتر = the thing you are talking about
• في المكتب = where it is

So the structure is:

[noun] + [prepositional phrase]

This is a very common way to make simple present-tense sentences in Arabic:

• The router
  • in the office
• understood as The router is in the office

It is a borrowed word from English, but it is commonly used in everyday Arabic.

That is very normal in Egyptian Arabic, especially for technology words. So even though the word comes from English, it behaves like an Arabic noun in the sentence:

• it can take الـ
• it can appear in normal Arabic sentence patterns

So الراوتر simply means the router.

In Egyptian Arabic, a very common negation is مش.

So you would say:

الراوتر مش في المكتب

That means:

• الراوتر = the router
• مش = not
• في المكتب = in the office

So: The router is not in the office.

In Egyptian Arabic, you can often make this a yes/no question just by using question intonation:

الراوتر في المكتب؟

You can also say:

هو الراوتر في المكتب؟

The first one is very natural in conversation. The meaning is understood from your tone of voice.

Not in this sentence.

Nothing here changes for gender:

• في stays the same
• there is no present-tense is
• the basic sentence structure stays the same

If you later use adjectives or pronouns with راوتر, it is usually treated as masculine by default.
