لدي سؤال خاص.

In Modern Standard Arabic, there is no everyday verb that works exactly like English to have in sentences like I have a question. Instead, Arabic usually expresses possession with a phrase such as:

• لدي = I have / with me / in my possession
• عندي = also I have / with me

So لدي سؤال خاص literally works more like A private/special question is with me, but in natural English it means I have a private question.

In MSA, لدي is quite common and slightly formal in tone.

لدي is made from:

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

So:

• لدى → with
• لدي → with me / I have

In fully vocalized Arabic, it is often written لَدَيَّ and pronounced roughly ladayya.

The final ـي is the attached pronoun meaning my / me.

Yes. عندي سؤال خاص is also correct and very common.

A simple comparison:

• لدي سؤال خاص = more formal, often associated with written or careful MSA
• عندي سؤال خاص = very common in speech and also widely understood in MSA

Both mean I have a private/special question. A learner will hear عندي very often in everyday Arabic.

In Arabic, adjectives usually come after the noun they describe.

So:

• سؤال = question
• خاص = private / special
• سؤال خاص = a private/special question

This is the normal Arabic order:

• noun + adjective

Unlike English, which usually has:

• adjective + noun

So Arabic says question private, not private question.

Because سؤال is indefinite, the adjective must also be indefinite.

Here is the pattern:

• سؤال = a question
• خاص = private / special
• سؤال خاص = a private/special question

If you made the noun definite, the adjective would also have to become definite:

• السؤال الخاص = the private/special question

This is an important rule in Arabic: the adjective agrees with the noun in definiteness.

The adjective خاص agrees with سؤال in several ways:

• gender: both are masculine
• number: both are singular
• definiteness: both are indefinite
• case: both would normally be nominative here in full grammatical analysis

So the full formal version with endings would be:

• لَدَيَّ سُؤَالٌ خَاصٌّ

In normal unvoweled writing, those endings are usually omitted:

• لدي سؤال خاص

In full formal Arabic, the sentence can be vocalized as:

• لَدَيَّ سُؤَالٌ خَاصٌّ

Here:

• سؤالٌ ends with -un
• خاصٌّ also ends with -un

This is because سؤال is analyzed as the main noun of the sentence, and خاص is its adjective, so both are nominative.

In most everyday writing, case endings are not written, and in most spoken Arabic they are not pronounced fully. So learners usually see:

• لدي سؤال خاص

without the endings.

سؤال is pronounced approximately suʔāl.

Important parts:

• سُ = su
• ؤ contains a hamza sound, a brief stop in the throat: ʔ
• ال gives the long ā sound

So it is not a smooth suwal. It is closer to su-ʔaal.

The hamza is written on ؤ here because of standard spelling rules. For a learner, the important thing is to hear and pronounce the little break: suʔāl.

خاص is pronounced approximately khāṣṣ.

A few details:

• خ = a rough kh sound, like the ch in Scottish loch or German Bach
• ا = long ā
• ص = an emphatic s
• the word is actually pronounced with a doubled final consonant in full form: khāṣṣ

So the word is stronger and heavier than a simple English kas or khas.

In full vocalization as an indefinite adjective, it would be خَاصٌّ.

It can mean different things depending on context, including:

• private
• special
• personal
• specific in some contexts

So سؤال خاص could mean:

• a private question
• a personal question
• sometimes a special/specific question, depending on the situation

The exact nuance comes from context. In many real conversations, it often suggests something personal or not for everyone.

Yes. The sentence starts with لدي, then gives the thing possessed:

• لدي = I have / with me
• سؤال خاص = a private/special question

So the structure is:

• possession phrase + possessed thing

This is a very normal Arabic pattern. English usually starts with the subject I, but Arabic often uses a possession phrase like لدي very naturally.

So instead of literally building I have X with a verb, Arabic commonly builds:

• with me is X
  which naturally means
• I have X
