الكابل جنب الراوتر.

A natural Egyptian-style pronunciation is roughly:

el-kabel ganb er-rāwter

A few helpful notes:

• ال is usually pronounced el- in Egyptian Arabic, not al-
• جنب is usually ganb in Egyptian
• In الراوتر, the ل of ال disappears in pronunciation because ر is a sun letter, so الراوتر sounds like er-rāwter

So you hear:

el-kabel ganb er-rāwter

In Arabic, especially in the present tense, the verb to be is usually not said.

So:

• الكابل جنب الراوتر literally looks like the cable next to the router
• but it naturally means The cable is next to the router

This is completely normal in both Egyptian Arabic and Modern Standard Arabic.

If you wanted past or future, then Arabic would express that differently, but in simple present descriptions, no separate is is needed.

Here, جنب means next to, beside, or by.

In this sentence it tells you the position of the cable relative to the router.

So:

• جنب = next to / beside

It is a very common everyday word in Egyptian Arabic.

For a learner, the easiest way to think of جنب here is as a preposition-like word meaning next to.

Historically, it comes from a noun related to side, but in everyday Egyptian Arabic it often behaves like a preposition in sentences such as:

• الكرسي جنب الباب = The chair is next to the door
• الموبايل جنب المفتاح = The phone is next to the key

So in practice, you can learn it as a location word meaning next to.

Because both nouns are definite:

• الكابل = the cable
• الراوتر = the router

In this sentence, we are talking about a specific cable and a specific router, not just any cable and any router.

If you removed ال, the meaning would become less definite, more like:

• كابل جنب راوتر = a cable next to a router

That is possible in some contexts, but your sentence clearly means the cable and the router.

No, they are borrowed words.

• كابل comes from cable
• راوتر comes from router

This is very common in Egyptian Arabic, especially for technology and modern objects.

Arabic often takes a foreign word and adds normal Arabic grammar to it, such as the definite article ال:

• كابل → الكابل
• راوتر → الراوتر

So even though the words are borrowed, they behave like normal nouns in the sentence.

Because ر is a sun letter.

In Arabic, when ال comes before a sun letter, the ل is not pronounced. Instead, the following consonant is emphasized or doubled in pronunciation.

So:

• written: الراوتر
• pronounced: er-rāwter or ar-rāwter

But with الكابل, ك is not a sun letter, so the ل is pronounced:

• الكابل → el-kabel

This is a very common pattern in Arabic.

Yes. That would be grammatically fine, but the meaning changes slightly.

• الكابل جنب الراوتر = The cable is next to the router
• الراوتر جنب الكابل = The router is next to the cable

In real life, the physical relationship is the same, but the sentence topic changes. The first sentence is about the cable; the second is about the router.

So the word order matters for what you are talking about first, not just for grammar.

It fits Egyptian Arabic very naturally, and it is also easy for speakers of other Arabic varieties to understand.

A few things make it feel especially natural in Egyptian:

• the use of everyday borrowed words like كابل and راوتر
• the common spoken word جنب

In Modern Standard Arabic, people might sometimes prefer more formal or technical vocabulary depending on the context, but this sentence is very normal in everyday speech.

Yes, depending on the exact meaning.

Some common alternatives are:

• بجانب = beside / next to
• قريب من = near
• حد in some colloquial uses = beside / next to

But جنب is one of the most common and natural everyday choices in Egyptian Arabic for next to.

So for a beginner, جنب is an excellent word to learn and use often.

No, not in Egyptian Arabic.

In spoken Egyptian Arabic, you do not use the case endings that learners may see in formal Arabic grammar. So the sentence is simply:

الكابل جنب الراوتر

No extra ending is needed on الكابل or الراوتر in normal speech.

That is one reason spoken Egyptian feels simpler than fully formal written Arabic in many everyday sentences.
