الإيجار الشهري في عقد الإيجار.

No. By itself, it is most naturally a noun phrase or a heading, not a full sentence.

It means something like:

• the monthly rent in the lease contract
• monthly rent in the rental agreement

In Arabic, headings, labels, and document items are often written as short phrases like this without a verb.

Because in Arabic, adjectives usually come after the noun they describe.

So:

• الإيجار = the rent
• الشهري = monthly

Together:

• الإيجار الشهري = the monthly rent

This is the normal order in Arabic:

• noun + adjective

not the English order:

• adjective + noun

Because Arabic adjectives must match the noun they describe in definiteness.

Here:

• الإيجار is definite because it has الـ
• so the adjective الشهري must also be definite

So:

• إيجار شهري = a monthly rent / monthly rent
• الإيجار الشهري = the monthly rent

This matching is very important in Arabic adjective phrases.

It is an adjective meaning monthly.

It comes from the noun شهر meaning month.

So:

• شهر = month
• شهري = monthly

In this phrase, الشهري describes الإيجار.

They are the same word, but they play different roles in the phrase.

1. The first الإيجار is the main noun:

   • الإيجار الشهري = the monthly rent

2. The second الإيجار is part of عقد الإيجار:

   • عقد الإيجار = the lease contract / rental agreement

So the whole phrase is structured like this:

• [الإيجار الشهري] = the monthly rent
• في [عقد الإيجار] = in the lease contract

Arabic often repeats a word where English might choose a synonym, and that is completely normal.

Yes. عقد الإيجار is an iḍāfa (genitive/construct phrase).

It literally means:

• عقد = contract
• الإيجار = the rent / the lease

Together:

• عقد الإيجار = the lease contract or the rental agreement

In an iḍāfa:

• the first noun usually does not take الـ
• the second noun can be definite
• the whole phrase becomes definite if the second noun is definite

So:

• عقد الإيجار is definite because الإيجار is definite

Because عقد الإيجار is an iḍāfa.

In an iḍāfa, the first noun does not usually take الـ, even when the whole phrase is definite.

So:

• عقد on its own = a contract
• عقد الإيجار = the lease contract

The definiteness comes from the second noun, الإيجار.

This is a very common feature of Arabic grammar.

في is the preposition meaning in.

So:

• في عقد الإيجار = in the lease contract

It shows that the monthly rent is something stated, mentioned, or specified in that contract.

A common pronunciation is:

al-ʾījār ash-shahriyy fī ʿaqd al-ʾījār

A few pronunciation notes:

• الشهري is pronounced ash-shahriyy because ش is a sun letter, so the l of الـ is not pronounced.
• ع in عقد is a consonant that does not exist in English, so learners usually need practice with it.
• الإيجار begins with a hamza sound: ʾījār.

Because ش is a sun letter.

With sun letters, the ل of الـ assimilates to the next consonant. So:

• written: الشهري
• pronounced: ash-shahriyy

But the spelling does not change.

This happens with many letters, such as:

• الشمس → ash-shams
• النور → an-nūr

That depends on the larger sentence, because this phrase by itself is not a full sentence.

If you were just reading it as an isolated heading or citation form, you would often pause without full case endings.

In a fully vocalized grammatical form, one possible reading is:

• الإيجارُ الشهريُّ في عقدِ الإيجارِ

Why?

• في makes عقد genitive: عقدِ
• in the iḍāfa, the second noun is also genitive: الإيجارِ
• the first part, الإيجار الشهري, could be nominative if it is a heading or subject-like phrase in context

But in real-life modern written Arabic, short document phrases are often written without vowel endings.

Some changes are possible, but the original order is the most natural for a neutral label or heading.

Original:

• الإيجار الشهري في عقد الإيجار

Possible variation:

• في عقد الإيجار، الإيجار الشهري...

That version sounds more like the beginning of a full sentence or a more marked structure.

For a form field, heading, or document item, the original order is better.

A very useful clue is definiteness matching.

In الإيجار الشهري:

• الإيجار has الـ
• الشهري also has الـ

That is typical of a noun + adjective structure.

In an iḍāfa, the first noun normally would not take الـ. So if this were an iḍāfa, you would expect something more like a different pattern, not الإيجار الشهري with both words definite.

So:

• الإيجار الشهري = noun + adjective
• عقد الإيجار = iḍāfa

This phrase contains both patterns side by side.
