الشنطة دي صغيرة.

A natural Egyptian Arabic pronunciation is roughly ish-shanṭa di soġayyara.

A simpler learner-friendly version:

• الشنطة → ish-shanta
• دي → di
• صغيرة → soghayyara

Notes:

• You may also hear esh-shanta instead of ish-shanta.
• The gh sound in soghayyara is like a French-style r or a gargled sound in the throat.
• The spelling is Arabic, but the actual Egyptian pronunciation is a bit different from Modern Standard Arabic.

Because ش is a sun letter.

In Arabic, when الـ comes before a sun letter, the l sound blends into the next consonant. So:

• ال + شنطة becomes pronounced
• اشِّنطة / ish-shanta

So the l is written, but you do not really hear it. Instead, the sh sound is doubled.

دي means this.

In this sentence, it refers to الشنطة, so:

• الشنطة دي = this bag

In Egyptian Arabic:

• ده = this for masculine nouns
• دي = this for feminine nouns

Since شنطة is feminine, you use دي.

Because that is the normal Egyptian Arabic pattern.

In English, you say:

• this bag

In Egyptian Arabic, you usually say:

• the bag this → الشنطة دي

So the demonstrative often comes after the noun in everyday Egyptian speech.

This is one of the most common word-order differences English speakers notice.

Because adjectives usually come after the noun in Arabic.

So:

• شنطة صغيرة = a small bag
• literally: bag small

That means the structure of the full sentence is:

• الشنطة = the bag
• دي = this
• صغيرة = small

So literally it feels like:

• the bag this small

But the natural English meaning is:

• this bag is small

Because the adjective has to match the noun in gender.

• شنطة is feminine
• so the adjective must also be feminine
• therefore you get صغيرة

Compare:

• الشنطة دي صغيرة = this bag is small
• الكتاب ده صغير = this book is small

A useful clue is the final ة on شنطة and صغيرة. That ending often marks feminine words/forms.

There is no separate word for is in the present tense here.

Arabic often leaves out the present-tense verb to be. So:

• الشنطة دي صغيرة literally looks like
• the bag this small

But it means:

• this bag is small

This is completely normal in Arabic.

Because in Egyptian Arabic, nouns with this/that are usually still made definite with الـ.

So the normal pattern is:

• الشنطة دي = this bag
• الكتاب ده = this book

For an English speaker, it may feel like Arabic is saying the bag this, and that is basically a good way to think about it.

Yes, but it means something a little different.

• الشنطة دي صغيرة = this bag is small
• دي شنطة صغيرة = this is a small bag

So when دي comes first, it can act more like this is...

That is an important difference:

• noun + دي + adjective → talking about this specific bag
• دي + noun + adjective → more like this is a...

It can depend on context.

In Egyptian Arabic, شنطة can mean:

• bag
• handbag
• sometimes purse

So the exact English word depends on what kind of bag people are talking about. The grammar of the sentence stays the same.
