جدول الدورة في الرسالة.

Because Arabic usually omits the present-tense verb to be.

So جدول الدورة في الرسالة is a normal present-tense nominal sentence meaning something like:

• The course schedule is in the message.

The structure is:

• جدول الدورة = the course schedule
• في الرسالة = in the message

In past or future, Arabic would use a verb such as كان for was.

Yes. جدول الدورة is an iḍāfa construction, often called a genitive or possession structure.

It works like this:

• جدول = schedule / timetable
• الدورة = the course

Together:

• جدول الدورة = the schedule of the course or more naturally the course schedule

In an iḍāfa:

• the first noun does not take ال
• the second noun often tells you whose/what kind of thing it is

Because in an iḍāfa, the first noun becomes definite through the second noun.

So:

• جدول by itself can mean a schedule
• جدول دورة = a course schedule
• جدول الدورة = the course schedule

Since الدورة is definite because it has ال, the whole phrase جدول الدورة is definite.

That is why Arabic does not say الجدول الدورة here.

Because the second noun in an iḍāfa is put in the genitive case.

In fully vowelled Arabic, this would be:

• جَدْوَلُ الدَّوْرَةِ

Here:

• جدولُ is nominative because it is the subject
• الدورةِ is genitive because it is the second part of the iḍāfa

If you are not yet studying case endings, you can still recognize the pattern without pronouncing them every time.

Because د is a sun letter.

With sun letters, the ل of ال is not pronounced separately. Instead, the following consonant is doubled.

So:

• الدورة is pronounced ad-dawra(tu/i), not al-dawra
• الرسالة is pronounced ar-risāla(tu/i), not al-risāla

This is only a pronunciation change. The spelling stays the same.

في الرسالة is a prepositional phrase meaning in the message.

• في = in
• الرسالة = the message / letter

In this sentence, it functions as the predicate: it tells you where the course schedule is.

So the overall structure is:

• جدول الدورة = subject
• في الرسالة = predicate

Because the preposition في requires the noun after it to be in the genitive case.

So in fully vowelled Arabic:

• في الرِّسالةِ

This is different from الدورةِ, which is genitive for another reason:

• الدورةِ is genitive because it is the second noun in an iḍāfa
• الرسالةِ is genitive because it comes after the preposition في

It can be understood as a full sentence in Arabic.

Arabic often makes complete present-tense sentences without a verb, especially with noun + prepositional phrase.

So this is naturally read as:

• The course schedule is in the message.

If you only saw جدول الدورة by itself, that would just be a noun phrase: the course schedule.

But once you add في الرسالة, it becomes a complete statement.

A careful formal pronunciation with case endings would be:

• jadwalu d-dawrati fī r-risālati

A learner-friendly version without focusing much on case endings is roughly:

• jadwal ad-dawra fi r-risala

Key pronunciation points:

• ج in MSA is often taught as j as in jam
• ow/aw in دورة
• ر is rolled or tapped
• ة at the end of الدورة and الرسالة is pronounced as t when the word is in a grammatical construction like this

Not always. دورة has a few related meanings depending on context, such as:

• course
• training course
• cycle
• round

In this sentence, course is the natural meaning because جدول الدورة commonly refers to a class or training schedule.

So learners should remember that Arabic words often have a wider range of meanings than a single English translation suggests.

Yes, but the meaning or emphasis may shift.

The given order:

• جدول الدورة في الرسالة

is a neutral way to say The course schedule is in the message.

You could also place the prepositional phrase first for emphasis:

• في الرسالة جدول الدورة

This can sound more like:

• In the message is the course schedule
• or The course schedule is in the message with extra emphasis on in the message

For learners, the original order is the easiest and most straightforward.
