यह डॉक्टर की पर्ची है।

A word-by-word breakdown is:

• यह = this
• डॉक्टर = doctor
• की = of / shows possession here
• पर्ची = slip, note, prescription
• है = is

So the structure is literally something like:

This doctor-of prescription is

Natural English: This is the doctor’s prescription or This is the doctor’s note/slip, depending on context.

Hindi uses का / की / के to show possession, somewhat like ’s or of in English.

Which one you use depends on the gender and number of the thing being possessed, not the owner.

Here, the possessed thing is पर्ची, and पर्ची is:

• feminine
• singular

So the correct form is की.

Compare:

• डॉक्टर का कमरा = the doctor’s room
  (कमरा is masculine singular)
• डॉक्टर की पर्ची = the doctor’s prescription/note
  (पर्ची is feminine singular)
• डॉक्टर के कागज़ = the doctor’s papers
  (कागज़ is plural)

No. In this sentence, की does not tell you the doctor’s gender.

That is a very common point of confusion for English speakers.

In डॉक्टर की पर्ची, की agrees with पर्ची, not with डॉक्टर.

So this sentence can mean:

• This is a male doctor’s prescription
• This is a female doctor’s prescription

The sentence itself does not specify the doctor’s gender.

पर्ची usually means a small written slip, note, or chit.

Depending on context, it can mean:

• slip
• note
• written prescription
• token
• small written paper

In a medical context, डॉक्टर की पर्ची very often means the doctor’s prescription or the prescription slip given by the doctor.

So the exact English translation depends on the situation.

Hindi and English often arrange information differently.

English says:

• This is the doctor’s prescription.

Hindi says:

• यह डॉक्टर की पर्ची है।

A helpful way to see the Hindi structure is:

• यह = this
• डॉक्टर की पर्ची = doctor’s prescription
• है = is

Hindi commonly puts the verb at the end, so है comes last.

Also, possession is shown inside the noun phrase:

• डॉक्टर की पर्ची = the doctor’s prescription

So the sentence order is very normal for Hindi.

Hindi does not usually use articles the way English does.

English needs words like:

• a
• an
• the

Hindi usually leaves them out, and the meaning is understood from context.

So यह डॉक्टर की पर्ची है। could be understood as:

• This is the doctor’s prescription
• This is a doctor’s prescription

In real context, it will usually be clear which meaning is intended.

Here, यह means this.

It is used for something near the speaker, or something being pointed out.

So:

• यह = this
• वह = that

In some contexts, यह can also function like he/she/it this one, depending on the sentence, but in this sentence it is most naturally this.

So यह डॉक्टर की पर्ची है। = This is the doctor’s prescription.

A simple pronunciation guide is:

yah doktor kee parchī hai

A slightly more careful transliteration is:

yah ḍokṭar kī parchī hai

Notes:

• यह sounds like yah
• की has a long ee sound
• पर्ची sounds roughly like par-chee
• है is often pronounced close to hai

If you say it smoothly, it sounds something like:

yah doktor kee parchee hai

Yes. That is possible.

Because पर्ची is a general word for a small written slip or note, the exact translation depends on context.

Possible translations include:

• This is the doctor’s prescription
• This is the doctor’s note
• This is the slip from the doctor

If you are in a clinic, pharmacy, or hospital setting, prescription is usually the best translation.

In everyday spoken Hindi, many speakers use ये for singular this in casual speech.

So you may hear:

• ये डॉक्टर की पर्ची है।

However, in careful standard written Hindi, यह is the usual singular form.

So for learning purposes:

• यह = standard singular this
• ये = standard plural these, but often used casually for singular this in speech

That means your original sentence, यह डॉक्टर की पर्ची है।, is the safest standard form.

No, that would be incorrect.

Since पर्ची is feminine singular, you need की, not का.

So:

• यह डॉक्टर की पर्ची है। = correct
• यह डॉक्टर का पर्ची है। = incorrect

If the possessed noun were masculine singular, then का would be right. For example:

• यह डॉक्टर का कमरा है। = This is the doctor’s room.

डॉक्टर is a loanword, ultimately from English doctor.

Hindi uses many everyday loanwords, especially for professions, technology, medicine, and modern life.

So even though it comes from English, it behaves like a normal Hindi noun in sentences:

• डॉक्टर आया। = The doctor came.
• डॉक्टर की पर्ची = the doctor’s prescription
• डॉक्टर से मिलो। = Meet the doctor.

This is very common and completely natural in Hindi.
