कृपया डॉक्टर की पर्ची दिखाइए।

Because का / की / के agrees with the thing being possessed, not with the possessor.

Here, the possessed noun is पर्ची, which is feminine singular, so Hindi uses की:

• डॉक्टर की पर्ची = the doctor’s slip/prescription

This does not mean the doctor is feminine. Even if the doctor is male, की is still correct because पर्ची is feminine.

For comparison:

• डॉक्टर का कमरा = the doctor’s room (कमरा is masculine singular)
• डॉक्टर के कागज़ = the doctor’s papers (कागज़ is plural)

पर्ची literally means a small slip of paper, note, or chit. In a medical context, डॉक्टर की पर्ची commonly means:

• a prescription
• a doctor’s slip
• sometimes a medical note or written instruction from the doctor

So the exact English translation depends on context, but in hospitals, clinics, or pharmacies, prescription is often the most natural meaning.

दिखाइए is a polite imperative form of दिखाना, which means to show.

So दिखाइए means:

• please show
• kindly show

It is respectful and appropriate when speaking to:

• a customer
• a patient
• an older person
• a stranger
• anyone in a formal situation

Less polite versions would be:

• दिखाओ = show (informal)
• दिखा = show (very informal/intimate)

So दिखाइए fits the polite tone of the sentence.

Yes. दिखाइए and दिखाइये are both used, and they mean the same thing.

• दिखाइए is the more standard modern spelling
• दिखाइये is also very common and widely understood

This kind of variation happens with some polite verb forms in Hindi. For a learner, it is safest to recognize both and use दिखाइए in writing.

कृपया means please. It makes the sentence more formal and polite.

So:

• डॉक्टर की पर्ची दिखाइए। = Show the doctor’s prescription.
• कृपया डॉक्टर की पर्ची दिखाइए। = Please show the doctor’s prescription.

A useful nuance: कृपया is quite formal, especially in writing, announcements, offices, hospitals, signs, and official speech. In everyday conversation, people often rely on the polite verb form itself, or use softer words like ज़रा in some contexts.

Because पर्ची here is the direct object of दिखाइए, and Hindi often leaves direct objects without को, especially when they are:

• inanimate
• non-specific in a special emphatic sense
• ordinary objects in a simple command

So पर्ची दिखाइए is completely normal: show the prescription.

If you wanted to say show the prescription to me, then को would appear with the recipient:

• मुझे डॉक्टर की पर्ची दिखाइए। = Please show me the doctor’s prescription.

So को is not missing here; it just is not needed for पर्ची in this sentence.

This order is very natural:

• कृपया = please
• डॉक्टर की पर्ची = the doctor’s prescription
• दिखाइए = show

Hindi usually puts the verb near the end, so this follows normal Hindi word order.

You may hear small variations, such as:

• डॉक्टर की पर्ची कृपया दिखाइए।
• कृपया पर्ची दिखाइए।

But कृपया डॉक्टर की पर्ची दिखाइए। is perfectly standard and clear.

Yes, it is polite and somewhat formal. You might hear it in places like:

• a hospital reception desk
• a clinic
• a pharmacy
• a medical records counter
• an insurance or registration office

It sounds like something a staff member might say to a patient or visitor. In very casual speech, a person might shorten it, but this full sentence is natural in professional settings.

Yes, depending on region and situation. Some alternatives are:

• पर्चा
• नुस्ख़ा
• प्रिस्क्रिप्शन (borrowed from English)

These are not always exact matches in every context, but they can overlap.

A very important grammar point: if the noun changes, का / की / के may also change.

For example:

• डॉक्टर की पर्ची — because पर्ची is feminine
• डॉक्टर का पर्चा — because पर्चा is masculine

So if you switch the noun, the possessive form may need to change too.

The base verb here is दिखाना, which means to show.

This is related in meaning to देखना, which means to see/look:

• देखना = to see
• दिखाना = to show, to cause someone to see

So:

• मैं देखता हूँ। = I see / I look.
• मैं दिखाता हूँ। = I show.

In your sentence, दिखाइए is the polite command form of दिखाना: please show.
