अपॉइंटमेंट के बाद जाँच होगी।

के बाद means after.

So:

• अपॉइंटमेंट = appointment
• के बाद = after
• जाँच होगी = there will be an examination/check-up

A very common Hindi pattern is:

**noun + के after lunch

• क्लास के बाद = after class

sentence mean the examination will be after the appointment?

Because जाँच is a feminine noun, and the future form of होना agrees with it.

In the future tense:

• होगा = masculine singular
• होगी = feminine singular
• होंगे / होंगी = plural forms

Since जाँच is feminine singular, we get:

• जाँच होगी

Compare:

• टेस्ट होगा। = The test will happen.
  (टेस्ट is usually treated as masculine.)
• जाँच होगी। = The examination/check-up will happen.
  (जाँच is feminine.)

Unfortunately, in Hindi you often have to learn a noun’s gender along with the noun.

For जाँच, the standard gender is feminine, so it takes feminine agreement:

• जाँच हुई = the examination happened
• जाँच होगी = the examination will happen
• अच्छी जाँच = a good examination

There is not always a reliable visual clue from the spelling alone, so it is best to memorize:

• जाँच — feminine

Hindi often uses होना in an impersonal or event-like way to mean:

• to happen
• to take place
• to be held

So जाँच होगी literally means the examination will happen, but in natural English that usually becomes:

• the examination will take place
• there will be an examination
• a check-up will be done

If you wanted to focus on someone actively doing the examination, Hindi might use a different structure, such as:

• डॉक्टर जाँच करेंगे। = The doctor will do the examination.

But the given sentence focuses on the event itself, not on who performs it.

Yes. अपॉइंटमेंट is a borrowed English word written in Devanagari.

This is very common in modern Hindi, especially for:

• medical contexts
• office contexts
• technology
• everyday urban speech

So अपॉइंटमेंट is perfectly normal Hindi usage in many situations.

A more Sanskritized or formal alternative might be possible depending on context, but in real life many speakers would naturally say अपॉइंटमेंट.

Good question. After a postposition like के, Hindi nouns usually go into the oblique form.

For example:

• लड़का → लड़के के बाद
• कमरा → कमरे के बाद

But many borrowed words, and many nouns in general, do not visibly change in the oblique form. अपॉइंटमेंट stays the same:

• अपॉइंटमेंट के बाद

So grammatically it is in the position where an oblique form is required, but its shape does not visibly change.

Yes, Hindi word order is somewhat flexible.

The given sentence:

• अपॉइंटमेंट के बाद जाँच होगी।

A very natural alternative is:

• जाँच अपॉइंटमेंट के बाद होगी।

Both mean essentially the same thing: The examination will be after the appointment.

The difference is mostly about emphasis:

• अपॉइंटमेंट के बाद जाँच होगी emphasizes after the appointment
• जाँच अपॉइंटमेंट के बाद होगी emphasizes the examination

Hindi often puts the verb near the end, but other parts can move around for focus.

It can cover several related meanings depending on context.

जाँच basically means:

• examination
• inspection
• checking
• investigation
• check-up

In a medical context, it often means:

• check-up
• examination
• test

So in this sentence, if the context is medical, check-up or examination is probably the best choice.

Context matters a lot in choosing the best English word.

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

So:

• जाँच होगी can mean an examination will happen, the examination will happen, or there will be an examination

The exact meaning depends on context.

That is why a single Hindi sentence may be translated into English in slightly different ways depending on the situation.

Yes, you may see both:

• जाँच
• जांच

The more careful standard spelling is जाँच, with the nasalization mark.

In everyday writing, especially informal typing, people sometimes write जांच. Both are commonly understood, but जाँच is the more standard form.
