क्या आपके पास दवा है?

Hindi often expresses possession with a near/with construction instead of a verb like English to have.

• आपके पास literally means near you / with you
• दवा है means there is medicine

So क्या आपके पास दवा है? literally works like:

• Is there medicine with you?

That is how Hindi commonly says Do you have medicine?

क्या marks the sentence as a yes/no question.

So:

• आपके पास दवा है। = You have medicine.
• क्या आपके पास दवा है? = Do you have medicine?

At the beginning, क्या does not mean what here. It is just a question marker.

No. It has two common uses:

1. At the start of a sentence: it can mark a yes/no question

   • क्या आपके पास दवा है? = Do you have medicine?

2. As a question word: it can mean what

   • क्या है? = What is it?

So in this sentence, क्या is not asking what medicine. It is simply making the whole sentence a question.

Because पास normally takes the oblique form of pronouns.

With आप, the oblique possessive form is आपके.

Compare:

• आपका नाम = your name
• आपकी किताब = your book
• आपके पास = with you / near you

So here आपके is used because of the expression के पास.

पास literally means near or close by, but in many sentences it means in someone’s possession or with someone.

Examples:

• मेरे पास पैसा है। = I have money.
• उसके पास समय नहीं है। = He/She does not have time.

So in your sentence, आपके पास दवा है? means Do you have medicine?

Hindi and English often organize sentences differently.

English:

• Do you have medicine?

Hindi:

• क्या + your-with + medicine + is

Hindi usually places the main verb or copula near the end. So है comes at the end, which is very normal.

दवा means medicine.

In this sentence, it can sound like:

• medicine in a general sense
• some medicine
• the medicine in context, if both speakers know which medicine is meant

Hindi often does not use articles like a, an, or the, so context decides the most natural English translation.

Good question. आप is used for you in a respectful or formal way, and it often behaves like a plural/respect form.

But in a possession sentence like this, है agrees with the thing being talked about: दवा.

Since दवा is singular, है is natural here:

• क्या आपके पास दवा है?

If the possessed thing were plural, you would usually get हैं:

• क्या आपके पास दवाइयाँ हैं? = Do you have medicines / any medicines?

Yes. दवा and दवाई are both used for medicine.

• दवा is very common
• दवाई is also very common in everyday speech

So these are both natural:

• क्या आपके पास दवा है?
• क्या आपके पास दवाई है?

Depending on region and context, one may sound more common than the other.

Yes, but the level of politeness changes.

• क्या आपके पास dवा है? = polite/formal/respectful
• क्या तुम्हारे पास दवा है? = informal, neutral with friends or younger people
• क्या तेरे पास दवा है? = very informal, intimate, or rough depending on tone and region

For someone you do not know well, आपके पास is the safest choice.

Yes. A few alternatives are possible, depending on tone and context:

• क्या आपके पास दवा है? = Do you have medicine?
• आपके पास दवा है? = Same meaning; in speech, intonation can make it a question even without क्या
• क्या आपके पास कोई दवा है? = Do you have any medicine?
• आपके पास दवाई है क्या? = Colloquial spoken style in many regions

The version you gave is standard and very natural.

The negative is:

• आपके पास दवा नहीं है। = You do not have medicine.
• As a question: क्या आपके पास दवा नहीं है? = Don’t you have medicine? / Do you not have medicine?

The word नहीं goes before है.

A simple learner-friendly pronunciation is:

• kyaa aap-ke paas da-vaa hai?

A few notes:

• क्या = kyaa
• आपके = aap-ke
• पास = paas with a long aa
• दवा = da-vaa
• है is often pronounced something like hai

Speak it smoothly:

• kyaa aapke paas davaa hai?

Yes. Because Hindi usually does not have articles like a or the, the exact English choice depends on context.

So क्या आपके पास दवा है? could mean:

• Do you have medicine?
• Do you have any medicine?
• Do you have the medicine?

If the context already makes a specific medicine clear, the medicine can be the best translation.

Hindi does not need a helper verb like English do to form this kind of question.

English needs:

• Do you have medicine?

Hindi simply uses:

• a question marker like क्या, or
• questioning intonation in speech

So Hindi can ask the question without an equivalent of English do.

Add कोई before दवा:

• क्या आपके पास कोई दवा है?

Here कोई means any / some in this context.

That version is especially natural if you are asking generally whether the person has any medicine available.
