لدي سؤال بشأن عقد الإيجار.

Arabic does not usually use a direct verb equivalent to English to have in this kind of sentence.

لدي literally means something like with me / in my possession:

• لدى = with, in the possession of
• ـي = my / me

So لدي سؤال literally means There is a question with me, which is the normal Arabic way to say I have a question.

A very similar form is عندي سؤال. In many contexts, that is also natural and common.

Both can often mean I have, but there is a slight difference in tone and usage.

• لدي is often felt to be a bit more formal or written.
• عندي is very common in everyday speech and also appears in writing.

So:

• لدي سؤال بشأن عقد الإيجار = a formal/neutral written way to say it
• عندي سؤال بشأن عقد الإيجار = also correct, often a bit more conversational

In Modern Standard Arabic, لدي fits very well in formal writing.

بشأن means regarding, concerning, or about.

So:

• سؤال بشأن... = a question regarding...

It is a formal expression, very common in written Arabic.
Other possible ways to say about include:

• عن = about
• حول = about / around / concerning

But بشأن sounds especially appropriate in formal contexts such as contracts, legal matters, and business communication.

عقد الإيجار means the lease contract or the rental contract.

Breaking it down:

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

Together they form an iḍāfa construction, often called a possessive or noun-link construction:

• عقد الإيجار = contract of the lease = lease contract

Arabic often expresses relationships between nouns this way instead of using of as a separate word.

This is a key feature of the iḍāfa construction.

In عقد الإيجار:

• the first noun is عقد
• the second noun is الإيجار

In an iḍāfa:

1. the first noun usually does not take الـ
2. the second noun determines whether the whole phrase is definite or indefinite

So because الإيجار is definite, the whole phrase عقد الإيجار is definite and means the lease contract.

Compare:

• عقد إيجار = a lease contract
• عقد الإيجار = the lease contract

Not in the English sense. It is an iḍāfa phrase, which can express several relationships, including possession, type, category, or association.

Here, عقد الإيجار means:

• lease contract
• rental contract
• literally, contract of renting/lease

So it is better to think of iḍāfa as a very common Arabic noun-link pattern, not only as possession.

Arabic has no separate indefinite article like English a/an.

So:

• سؤال can mean a question
• السؤال means the question

In this sentence, سؤال is indefinite, so it naturally means a question.

This order is natural because Arabic is presenting the idea in pieces:

• لدي = I have
• سؤال = a question
• بشأن عقد الإيجار = regarding the lease contract

So the sentence is structured as: I-have + a question + regarding the lease contract

Arabic word order is flexible, but this version is very normal and clear.
You could move things for emphasis in some contexts, but this standard order is the safest choice for learners.

A simple pronunciation guide is:

ladayya su'ālun bisha'ni `aqdi al-ījār

A few notes:

• لدي is usually pronounced ladayya
• سؤال has a glottal stop in the middle: su'āl
• بشأن also has a glottal stop: bisha'n
• عقد begins with ع, a sound that does not exist in English
• الإيجار is al-ījār

In normal pausal pronunciation, many case endings are not fully pronounced, so learners often hear something closer to:

ladayya su'āl bisha'n `aqd al-ījār

Yes. In fully vocalized formal Arabic, the sentence could appear with case endings.

A careful grammatical version would be roughly:

لديَّ سؤالٌ بشأنِ عقدِ الإيجارِ

Why?

• سؤالٌ is indefinite and nominative here
• after بشأنِ, the following noun phrase is in the genitive:
  • عقدِ
  • الإيجارِ

However, in normal everyday writing, these short vowel endings are usually omitted.

Both spellings relate to pronunciation and orthographic detail.

• لدي is the common everyday spelling
• لديّ shows the doubled y sound more explicitly

The pronunciation is basically ladayya, not just laday.
So the form with shadda on ي helps show that pronunciation more clearly.

Yes, often you can.

• لدي سؤال عن عقد الإيجار = I have a question about the lease contract

This is natural and common.
The difference is mostly in style:

• عن = simpler, more everyday
• بشأن = more formal, more official-sounding

In a business email or formal request, بشأن is an excellent choice.

It is essentially a nominal-style statement built around a prepositional expression rather than a simple verb like to have.

You can think of it as:

• لدي = a phrase meaning I have / with me
• سؤال = the thing possessed
• بشأن عقد الإيجار = additional information describing the question

So although the English translation uses the verb have, the Arabic sentence is not built the same way as an English verb sentence. That is very common in Arabic and worth getting used to early.
