العنوان ده صح، وهو اللي في الرسالة.

Here, العنوان means the address.

In Egyptian Arabic, عنوان can also mean title or heading in other contexts, so learners often wonder about that. In this sentence, the context tells you it means address.

In Egyptian Arabic, demonstratives like ده often come after the noun:

• العنوان ده = this address
• الرسالة دي = this message/letter

That post-noun pattern is very common in everyday speech.

By contrast, ده العنوان usually means something more like this is the address, where ده is part of the sentence structure rather than just modifying the noun.

So:

• العنوان ده صح = This address is correct
• ده العنوان = This is the address

ده is the Egyptian Arabic masculine singular demonstrative, meaning this.

Since العنوان is masculine singular, ده is the right form.

Some common Egyptian demonstratives are:

• ده = this (masculine)
• دي = this (feminine)
• دول = these

So العنوان ده literally means the address this, but naturally it means this address.

صح means correct, right, or true.

So:

• العنوان ده صح = This address is correct

In Egyptian Arabic, صح is extremely common in everyday speech. It can also be used by itself to mean right? or correct? depending on tone.

Compared with more formal Arabic, you may also see صحيح, but صح is very natural in Egyptian conversation.

هو here means it/he and refers back to العنوان.

So:

• وهو = and it is

The full idea is:

• العنوان ده صح، وهو اللي في الرسالة
• This address is correct, and it is the one in the message

In English, we can sometimes skip pronouns, but Arabic often keeps them more clearly. Here هو helps set up the next part of the sentence: it is the one...

اللي is a very common Egyptian relative word meaning that, which, or the one that.

In this sentence:

• هو اللي في الرسالة
• literally: it is the one that is in the message

Egyptian Arabic uses اللي for many situations where English uses different words like who, which, and that.

Examples:

• الولد اللي هناك = the boy who is over there
• الكتاب اللي اشتريته = the book that I bought
• هو اللي في الرسالة = it’s the one in the message

في الرسالة means in the message or in the letter.

• في = in
• الرسالة = the message / the letter

Depending on context, رسالة could mean:

• a text message
• an email/message
• a letter

So اللي في الرسالة means the one that is in the message.

Because ر is a sun letter. In Arabic, when الـ comes before a sun letter, the l sound of ال assimilates to the next consonant.

So:

• الرسالة is written with ال
• but pronounced roughly er-risāla / ir-risāla

The spelling does not change, only the pronunciation.

و means and.

So:

• وهو = and it is

This connects the two parts:

1. العنوان ده صح
2. وهو اللي في الرسالة

Together: This address is correct, and it’s the one in the message.

Usually, in this exact structure, هو is very helpful and natural.

• وهو اللي في الرسالة = and it’s the one in the message

If you removed هو, you would get:

• واللي في الرسالة

That sounds incomplete here, because اللي في الرسالة by itself means the one that is in the message, but the sentence needs something like it is before it.

So هو makes the sentence complete and natural.

Yes. It is basically a relative expression meaning:

• the one that is in the message

Breakdown:

• اللي = that / which / the one that
• في الرسالة = in the message

So هو اللي في الرسالة literally means it is the one that is in the message.

In smoother English, that becomes it’s the one in the message.

A natural Egyptian-style pronunciation would be roughly:

el-ʿonwān da ṣaḥḥ, we howwa lli fe r-resāla

A few notes:

• العنوان → el-ʿonwān
• ده → da
• صح → ṣaḥḥ with a strong ḥ
• وهو → often we howwa
• اللي → illi or lli
• في → fe
• الرسالة → r-resāla because of sun-letter assimilation

Yes, it is clearly Egyptian-style colloquial Arabic.

Signs of that include:

• ده for this
• اللي as the everyday relative word
• صح as a common colloquial word for correct

A more formal or Modern Standard Arabic version would look different, for example using forms like هذا instead of ده.

So this sentence is very natural in spoken Egyptian Arabic.
