सेट अब शुरू होता है।

Because Hindi often borrows English words and writes them in Devanagari script.

• सेट is the Hindi spelling of set
• It is pronounced roughly like set
• In modern Hindi, especially in sports, media, entertainment, and everyday conversation, this is very common

So this is not unusual at all. It is simply an English loanword being used as part of a Hindi sentence.

अब means now.

In सेट अब शुरू होता है, it adds the idea that the set begins now or from this point.

Hindi word order is fairly flexible, so you may also see:

• अब सेट शुरू होता है
• सेट शुरू होता है अब — less common in neutral speech, but possible in certain contexts

The placement of अब in the middle is perfectly normal.

Because शुरू होना means to begin / to start in the sense that something starts by itself or comes into a started state.

So:

• शुरू होता है = starts / begins
• शुरू करता है = starts something / begins doing something

That is the difference between an intransitive and a transitive idea.

Compare:

• फिल्म शुरू होती है। = The film starts.
• वह फिल्म शुरू करता है। = He starts the film.

In your sentence, the set is the thing that begins, so शुरू होता है is the right pattern.

Because it agrees with सेट, which is being treated as a masculine singular noun here.

Hindi habitual forms agree with the subject in sentences like this:

• masculine singular: होता है
• feminine singular: होती है
• masculine plural: होते हैं
• feminine plural: होती हैं

Since सेट is understood as masculine singular, the sentence uses होता है.

होता है is the habitual present form of होना.

In this sentence, शुरू होता है works as a unit meaning:

• starts
• begins
• does begin in a general or scheduled sense

A useful way to think about it is:

• शुरू = started / beginning
• होता है = happens / becomes / is in the habitual present

Together, शुरू होता है gives the standard Hindi way to say starts / begins.

It most naturally means something like starts now or now begins.

But there is an important nuance:

• शुरू होता है is a habitual/simple present form
• In many real situations, Hindi speakers might prefer शुरू हो रहा है for something happening right now

So:

• सेट अब शुरू होता है। = The set now starts / The set begins now
• सेट अब शुरू हो रहा है। = The set is starting now

Your sentence is grammatical, but depending on context, the progressive form may sound more natural for an event beginning at this exact moment.

Not usually in this kind of sentence.

शुरू is commonly used with होना or करना:

• शुरू होना = to begin / to start
• शुरू करना = to start something / to begin doing something

So in सेट अब शुरू होता है, the actual verbal part is the combination शुरू होता है, not शुरू alone.

Yes, absolutely.

That version is often more natural if you mean the set is beginning right at this moment.

Compare:

• सेट अब शुरू होता है। = the set starts now / the set begins now
• सेट अब शुरू हो रहा है। = the set is starting now

The first is more like a simple present statement.
The second emphasizes an action currently in progress.

No, not completely.

Hindi has more flexible word order than English, although some orders sound more natural than others. These are all possible depending on emphasis:

• सेट अब शुरू होता है।
• अब सेट शुरू होता है।

The original version gives a natural flow where अब highlights the time shift: the set now begins.

A simple learner-friendly pronunciation guide:

• शुरू = shu-roo
• होता = ho-taa
• है = hai

So the whole phrase sounds roughly like:

set ab shu-roo ho-taa hai

A slightly more natural transliteration is:

set ab shurū hotā hai

Sometimes loanwords can vary in gender depending on region, speaker, and meaning, but in many common uses सेट is treated as masculine.

That is why होता है sounds normal here.

With borrowed nouns, gender is not always fully predictable, so the best approach is to learn the most common usage you hear in context.

No. You can say:

• सेट शुरू होता है।

That simply removes the idea of now.

So the difference is:

• सेट शुरू होता है। = the set starts / the set begins
• सेट अब शुरू होता है। = the set starts now / the set begins now

It is grammatical and understandable, but the naturalness depends on context.

A native speaker might more commonly say:

• सेट अब शुरू हो रहा है। if it is beginning right now
• अब सेट शुरू होगा। if it is about to start
• सेट अब शुरू होता है। in a more general, descriptive, or scheduled sense

So the sentence is not wrong, but learners should know that Hindi often chooses different aspect forms depending on whether something is generally true, scheduled, or happening at this moment.
