फार्मासिस्ट दवा की दुकान में डॉक्टर की पर्ची देख रहा है।

They are doing the same general job: linking one noun to another, roughly like of or 's in English.

• दवा की दुकान = medicine shop / shop of medicine
• डॉक्टर की पर्ची = doctor's prescription

In both cases, की agrees with the noun that comes after it:

• दुकान is feminine singular, so की
• पर्ची is feminine singular, so की

If the following noun were masculine singular, you would often see का instead:

• डॉक्टर का कमरा = the doctor's room

Literally, it means shop of medicine. In natural English, that is pharmacy, chemist's shop, or drugstore, depending on the variety of English.

So:

• दवा = medicine
• दुकान = shop
• दवा की दुकान = medicine shop / pharmacy

This is a very normal Hindi way to express this idea.

में is a postposition meaning in, inside, or sometimes at depending on context.

So:

• दवा की दुकान में = in the pharmacy

Hindi uses postpositions after nouns, where English often uses prepositions before nouns. That is why Hindi says:

• दुकान में = in the shop

not the other way around.

Because this sentence is in the present progressive: देख रहा है = is looking / is seeing.

In Hindi, ने is typically used with the subject of a transitive verb in the perfective aspect, not usually in the present progressive.

Compare:

• फार्मासिस्ट डॉक्टर की पर्ची देख रहा है।
  The pharmacist is looking at the doctor's prescription.

• फार्मासिस्ट ने डॉक्टर की पर्ची देखी।
  The pharmacist saw the doctor's prescription.

So the absence of ने here is normal.

This is the common Hindi way to form the present progressive.

It breaks down like this:

• देख = verb stem of देखना (to see / to look at)
• रहा = progressive participle
• है = is

So देख रहा है means is looking at or is seeing.

A few related forms:

• देख रहा है = he is looking
• देख रही है = she is looking
• देख रहे हैं = they are looking / he is looking (respectful)

Because in this kind of sentence, the verb agrees with the subject, not with those other nouns.

Here the subject is फार्मासिस्ट, and the sentence is treating that person as masculine singular, so we get:

• देख रहा है

If the pharmacist were female, it would be:

• फार्मासिस्ट ... देख रही है।

So रहा / रही / रहे depends on the subject here.

Yes, in actual sentences it behaves according to the gender of the person being talked about.

The noun itself is a loanword, but the verb still shows agreement:

• फार्मासिस्ट ... देख रहा है। = a male pharmacist is looking
• फार्मासिस्ट ... देख रही है। = a female pharmacist is looking

So even though the word is borrowed, Hindi grammar still treats the person as masculine or feminine when needed.

पर्ची literally means a slip of paper, note, or small written slip. In medical contexts, it commonly means a prescription.

So:

• डॉक्टर की पर्ची = the doctor's prescription

In other contexts, पर्ची could mean other kinds of slips or notes, but here the medical setting makes prescription the natural meaning.

Hindi does not have articles that work exactly like English a/an and the.

So a sentence like this can be understood as:

• A pharmacist is looking at a doctor's prescription in a pharmacy
• or The pharmacist is looking at the doctor's prescription in the pharmacy

The exact choice depends on context. Hindi often leaves definiteness to be understood from the situation rather than marking it with separate words.

Not completely. Hindi usually prefers the verb at the end, but the order of other elements can move around for emphasis.

This sentence has:

• फार्मासिस्ट = subject
• दवा की दुकान में = location
• डॉक्टर की पर्ची = object
• देख रहा है = verb

A very normal pattern is:

• Subject + place + object + verb

But you could also hear:

• फार्मासिस्ट डॉक्टर की पर्ची दवा की दुकान में देख रहा है।

That still works, though the emphasis may feel slightly different. The most important rule is that the main verb usually stays near the end.

In this sentence, to look at is usually the best translation.

That is because the pharmacist is actively examining the prescription, not just passively seeing it.

So:

• पर्ची देख रहा है here means is looking at the prescription or is checking the prescription

Hindi देखना can cover both see and look at, and context tells you which English verb fits best.
