الطوق جنب السلسلة.

A common Egyptian pronunciation is eṭ-ṭōʔ gamb es-selsela.

A few quick notes:

• ج in Egyptian is usually a hard g, so جنب sounds like gamb.
• ق in many Egyptian words is pronounced as a glottal stop ʔ, so طوق ends like ṭōʔ.
• The ال in both nouns assimilates because ط and س are sun letters, so you hear eṭ-ṭ... and es-s..., not el-....

In Arabic, present-tense sentences like this usually do not use a separate word for is.

So instead of saying:

• The collar is next to the chain

Arabic simply says:

• The collar next to the chain

This is very normal. In past or future contexts, Arabic can use verbs such as forms of كان.

Here جنب means next to, beside, or by.

In Egyptian Arabic, it is very commonly used to show location:

• جنب البيت = next to the house
• جنب العربية = next to the car

So in this sentence, جنب connects the two nouns and tells you where the first one is in relation to the second.

That is a very Egyptian feature.

Two things are happening:

• ج is pronounced g in Egyptian Arabic.
• The n before b is commonly heard as m, so janb becomes gamb in natural speech.

So the spelling stays جنب, but the everyday Egyptian pronunciation is gamb.

Because of sun-letter assimilation.

The Arabic definite article is written ال, but when it comes before certain letters, the l sound disappears and the next consonant is doubled.

Here:

• الطوق is pronounced eṭ-ṭōʔ
• السلسلة is pronounced es-selsela

That happens because ط and س are both sun letters.

Because both nouns are definite here.

• الطوق = the collar
• السلسلة = the chain

Using ال shows that the speaker is talking about specific, known things, not just any collar or any chain.

If you remove ال, the noun usually becomes indefinite:

• طوق = a collar
• سلسلة = a chain

Yes. That would also be grammatical.

• الطوق جنب السلسلة
• السلسلة جنب الطوق

Both describe the same spatial relationship, but the first noun is the one being presented as the topic or starting point.

In English, this is a little like the difference between:

• The collar is next to the chain
• The chain is next to the collar

Same basic scene, different focus.

In Egyptian Arabic, a common pronunciation is eṭ-ṭōʔ.

Breakdown:

• ط = an emphatic t
• و gives a long vowel, often heard as ō
• ق is often a glottal stop ʔ in Egyptian speech

So it does not sound like a full q sound in everyday Egyptian pronunciation.

A common Egyptian pronunciation is es-selsela.

Important point about the final ة:

• At the end of a phrase, it is usually pronounced -a
• So سلسلة sounds like selsela, not selselat

That final ة can sound more like -t in some grammatical environments, especially in more formal Arabic, but here at the end of the sentence it is just -a.

Other Arabic speakers would very likely understand it, because the words themselves are not uniquely Egyptian.

What makes it feel Egyptian is mainly the pronunciation:

• جنب pronounced gamb
• ق in طوق pronounced as ʔ

In more formal Modern Standard Arabic, the pronunciation would be different, especially for جنب and ق, but the written sentence is still very clear and widely understandable.
