जैसे ही सेट खत्म होगा, रेफ़री स्कोर दिखाएगा।

जैसे ही means as soon as.

It introduces an action that happens immediately after another action. So the pattern is:

जैसे ही X..., Y...
= As soon as X..., Y...

In your sentence:

जैसे ही सेट खत्म होगा, रेफ़री स्कोर दिखाएगा।
= As soon as the set ends, the referee will show the score.

So जैसे ही signals a very close time relationship between the two events.

In Hindi, खत्म होना is a very common way to say to end or to be finished.

Here:

• खत्म = finished / over
• होना = to be / to happen / to become

Together, खत्म होना literally works like to become finished, which in natural English is to end or to be over.

So:

• सेट खत्म होगा = the set will end / will be over

This is a very normal Hindi structure. Hindi often uses an adjective-like word plus होना where English uses a single verb.

Because both actions are referring to the future.

In English, we often say:

• As soon as the set ends, the referee will show the score.

Notice that English uses present tense in the as soon as clause (ends) even though it refers to the future.

Hindi does not usually do that here. With जैसे ही, Hindi commonly uses future forms in both clauses when talking about future events:

• जैसे ही सेट खत्म होगा, रेफ़री स्कोर दिखाएगा।

So this is a key difference from English:

• English: as soon as it ends
• Hindi: जैसे ही ... खत्म होगा

Because होगा agrees with सेट, and सेट is being treated as masculine singular.

Hindi future forms of होना change according to gender and number:

• होगा = masculine singular
• होगी = feminine singular
• होंगे = masculine plural / respectful singular in some contexts
• होंगी = feminine plural

Since सेट here is one singular masculine noun, we get:

• सेट खत्म होगा

If the noun were feminine, you would use होगी instead.

दिखाएगा is the future tense of दिखाना = to show.

It agrees with the subject रेफ़री.

So:

• रेफ़री दिखाएगा = the referee will show

Here, रेफ़री is being treated as masculine singular, so the verb is दिखाएगा.

If the referee were female, you would normally say:

• रेफ़री स्कोर दिखाएगी।

So the ending -एगा shows masculine singular future.

The basic Hindi word order is usually Subject + Object + Verb.

So here:

• रेफ़री = subject
• स्कोर = object
• दिखाएगा = verb

That gives:

रेफ़री स्कोर दिखाएगा।
literally: Referee score will-show.

This is normal Hindi word order. English usually prefers Subject + Verb + Object, but Hindi usually puts the verb at the end.

They are commonly used in Hindi, but they are borrowed from English.

This happens a lot in modern Hindi, especially in sports, technology, business, and everyday speech.

So:

• सेट = set
• रेफ़री = referee
• स्कोर = score

A native speaker would understand these very easily, especially in a sports context. This kind of borrowing is completely normal.

Yes. You could make it more formal by replacing some words.

For example:

• खत्म could become समाप्त
• रेफ़री could become निर्णायक in some contexts
• स्कोर could become अंक or अंकतालिका, depending on the context

A more formal version might be:

जैसे ही सेट समाप्त होगा, निर्णायक अंक दिखाएगा।

But in real sports commentary or everyday usage, the original sentence with सेट, रेफ़री, and स्कोर sounds very natural.

Yes, you could, and it would still sound natural.

Compare:

• सेट खत्म होगा = the set will end / will be over
• सेट खत्म हो जाएगा = the set will get over / will end up finishing

Both are possible.
खत्म होगा is a bit simpler and more direct.
खत्म हो जाएगा can sometimes sound a little more emphatic or complete.

In many situations, the difference is small, and both would be understood easily.

The comma is helpful, but it is not the most important part grammatically.

It separates the two clauses:

• जैसे ही सेट खत्म होगा
• रेफ़री स्कोर दिखाएगा

This makes the sentence easier to read, especially in writing. In speech, the pause after the first clause would usually make the structure clear even without a comma.

So the comma is natural and useful, but the meaning mainly comes from the words and verb forms, especially जैसे ही.

The verb endings would change to match the relevant noun or subject.

Examples:

1. If सेट were feminine:

   • जैसे ही ... खत्म होगी

2. If the referee were female:

   • जैसे ही सेट खत्म होगा, रेफ़री स्कोर दिखाएगी।

3. If the subject were plural:

   • जैसे ही सेट खत्म होगा, रेफ़री स्कोर दिखाएँगे।
     This could also be used for a respectful singular person in some contexts.

So when reading Hindi, it is always useful to check which noun the verb is agreeing with.
