التغطية ورسوم التركيب في الرسالة.

Arabic often has no written or spoken present-tense to be in simple statements.

So التغطية ورسوم التركيب في الرسالة can be understood as a nominal sentence:

• التغطية ورسوم التركيب = the subject
• في الرسالة = the predicate, meaning in the message

So the sentence can mean The coverage and the installation fees are in the message without any separate word for are.

Because و meaning and is written as a prefix in Arabic. It usually attaches directly to the following word.

So:

• و + رسوم → ورسوم

This is completely normal Arabic spelling.

الـ is the Arabic definite article, usually equivalent to the.

So:

• تغطية = coverage / covering
• التغطية = the coverage

Arabic often uses definiteness more freely than English, so even if English might just say coverage, Arabic may still use التغطية.

Because رسوم التركيب is an iḍāfa construction, often called a possessive or noun-link construction.

In an iḍāfa:

• the first noun normally does not take الـ
• the second noun can make the whole phrase definite

So:

• رسوم التركيب = installation fees / the installation fees

Since التركيب is definite, the whole phrase is definite. That is why Arabic does not say الرسوم التركيب here.

It is an iḍāfa phrase:

• رسوم = fees
• التركيب = the installation

Together, literally: fees of the installation

More natural English: installation fees

This is a very common Arabic structure. English often uses of or just puts one noun before another, while Arabic uses iḍāfa.

Here رسوم means fees or charges.

Its singular is:

• رَسْم = fee / charge

Its plural is:

• رُسوم = fees / charges

Arabic often uses the plural when talking about kinds of charges or fees, just as English often says fees rather than fee.

Also, رسوم can mean drawings in other contexts, but here رسوم التركيب clearly means installation fees.

No. In this sentence they are nouns.

More specifically, both are verbal nouns or action nouns:

• التغطية comes from a verb meaning to cover
• التركيب comes from a verb meaning to install / assemble

So they name actions or concepts:

• التغطية = coverage / covering
• التركيب = installation

This is very common in Modern Standard Arabic.

It means in the message.

Breakdown:

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

Depending on context, رسالة can mean:

• message
• letter
• email

So the exact English choice depends on the situation.

A careful pronunciation is:

at-taghṭiya wa-rusūm at-tarkīb fī ar-risālah

A few useful notes:

• التغطية is pronounced at-taghṭiya, not al-taghṭiya, because ت is a sun letter
• التركيب is pronounced at-tarkīb for the same reason
• الرسالة is pronounced ar-risālah, because ر is also a sun letter

So the l of الـ assimilates to the next consonant in these words.

A likely fully vowelled form is:

التغطيةُ ورسومُ التركيبِ في الرسالةِ

Why:

• التغطيةُ is nominative as part of the subject
• رسومُ is also nominative because it is joined to the subject with و
• التركيبِ is genitive because it is the second term of an iḍāfa
• الرسالةِ is genitive because it comes after في

In normal everyday printed Arabic, these short vowels are usually not written.

Yes. The most natural reading is that في الرسالة applies to the whole coordinated phrase:

• التغطية
• ورسوم التركيب

So the meaning is that both the coverage and the installation fees are mentioned or found in the message.

That is a very normal way for Arabic to structure a sentence like this.
