الهدوم دي جديدة.

A common Egyptian pronunciation is:

il-hudūm دي gadīda
or more fully: il-hudūm di gadīda

Notes:

• الـ is usually pronounced il- in Egyptian Arabic.
• هدوم sounds like hudūm.
• دي sounds like di.
• جديدة in Egyptian is commonly pronounced gadīda, because ج is usually g in Egypt.

So the whole sentence sounds roughly like: il-hu-DOOM di ga-DEE-da.

Word by word:

• الهدوم = the clothes
• دي = these
• جديدة = new

Even though the full meaning is already known, it helps to see the structure:

• الهدوم دي = these clothes
• جديدة = are new

So the sentence structure is basically:

[noun phrase] + [adjective/predicate]

In Egyptian Arabic, demonstratives like دي often come after the noun.

So:

• الهدوم دي = these clothes

This is very normal in Egyptian Arabic. English says these clothes, but Egyptian Arabic often says something more like the clothes these.

This noun + demonstrative pattern is extremely common:

• البنت دي = this girl
• العربية دي = this car
• الهدوم دي = these clothes

Because in Arabic, the verb to be is usually omitted in the present tense.

So English:

• The clothes are new

Egyptian Arabic:

• الهدوم دي جديدة

There is no separate present-tense word for is/are here.

This happens all the time:

• أنا تعبان = I am tired
• هي كويسة = She is fine
• الجو حر = The weather is hot

So the sentence is perfectly complete without a word for are.

This is one of the most important grammar points here.

In Arabic, non-human plurals are very often treated grammatically like feminine singular.

Since الهدوم means clothes and refers to things, not people, the adjective often appears in the feminine singular form:

• جديد = masculine singular
• جديدة = feminine singular

So:

• الهدوم دي جديدة is correct

This same pattern appears a lot:

• الكتب دي جديدة = These books are new
• العربيات دي سريعة = These cars are fast

Even though the meaning is plural, the grammar often uses feminine singular agreement for non-human plurals.

Yes, دي is basically the feminine singular demonstrative in Egyptian Arabic.

But because non-human plurals often behave like feminine singular, دي is natural with الهدوم.

So:

• الهدوم دي = these clothes

This may feel strange at first, but it matches the same agreement pattern as جديدة.

For comparison:

• البنت دي = this girl
• الهدوم دي = these clothes

Even though one is singular and one is plural in meaning, both can take دي because non-human plurals often use feminine singular grammar.

Because الهدوم is definite here, but جديدة is a predicate adjective.

• الهدوم = the clothes
• جديدة = new

In a sentence like The clothes are new, the adjective is usually not made definite in Arabic.

So:

• الهدوم دي جديدة = These clothes are new

But if you wanted to say the new clothes, where the adjective is directly describing the noun inside one noun phrase, then the adjective would also take الـ:

• الهدوم الجديدة = the new clothes

So compare:

• الهدوم دي جديدة = These clothes are new
• الهدوم الجديدة = the new clothes

In Egyptian Arabic, people often use الـ with nouns in this kind of structure, so الهدوم دي is the most natural form.

Using هدوم دي without الـ is generally less standard in this pattern and may sound incomplete or less natural depending on context.

So for a learner, it is safest to use:

• الهدوم دي جديدة

That is the normal, natural Egyptian way to say it.

هدوم means clothes in Egyptian Arabic, and it functions as a plural or collective noun.

It does not behave exactly like a simple English plural in every grammatical way, because Arabic has its own agreement rules. The key thing for learners is:

• It refers to multiple items of clothing.
• As a non-human plural, it often takes feminine singular agreement.

So in practice, what matters most is remembering the whole pattern:

• الهدوم دي جديدة

In Modern Standard Arabic, the common word for clothes is usually الثياب or الملابس, not الهدوم.

A more MSA-style sentence would be something like:

• هذه الثياب جديدة
• هذه الملابس جديدة

Important differences:

• Egyptian Arabic uses دي
• MSA uses هذه
• Egyptian ج is usually pronounced g
• MSA ج is usually pronounced j in careful speech

So الهدوم دي جديدة is clearly Egyptian colloquial, not formal MSA.

Usually, the most natural reading is:

• These clothes are new

If you want to say these are new clothes, Arabic would usually use a different structure, often one that more clearly introduces new clothes as a noun phrase.

So for learners, it is best to understand:

• الهدوم دي جديدة = These clothes are new

not primarily These are new clothes.

A very useful pattern is:

[definite noun] + [demonstrative] + [adjective/predicate]

Example:

• الهدوم دي جديدة

You can reuse it with many nouns:

• العربية دي سريعة = This car is fast
• الشنطة دي تقيلة = This bag is heavy
• الكتب دي مفيدة = These books are useful

And this sentence also teaches an important rule:

Non-human plurals often take feminine singular agreement in Egyptian Arabic.

So this one example gives you several big lessons at once:

• demonstrative after the noun
• no present-tense is/are
• feminine singular agreement with non-human plurals
