नेट कोर्ट के बीच में है।

Word by word:

• नेट = net
• कोर्ट = court
• के बीच में = in the middle of / between
• है = is

So the structure is literally something like: The net is in the middle of the court.

Hindi often places location information before the verb, and the verb usually comes at the end.

English: The net is in the middle of the court.

Hindi: नेट कोर्ट के बीच में है। Literally: Net court of middle in is.

This is normal Hindi word order:

• subject: नेट
• location phrase: कोर्ट के बीच में
• verb: है

Because बीच is being used in a postpositional phrase, and the noun before it takes the oblique form plus the appropriate postposition-like linker.

With masculine singular nouns like कोर्ट, the direct form and oblique form are often the same in writing, but the connector used here is के:

• कोर्ट के बीच में = in the middle of the court

You should learn X के बीच में as a common pattern meaning:

• in the middle of X
• among X
• sometimes between X and Y in other contexts

So के here is part of the natural expression के बीच में.

बीच means middle or between, and में means in.

Together:

• बीच में = in the middle
• sometimes also in between

So:

• कमरे के बीच में = in the middle of the room
• सड़क के बीच में = in the middle of the road

In your sentence:

• कोर्ट के बीच में = in the middle of the court

Not as written.

कोर्ट के बीच में with singular कोर्ट means in the middle of the court.

If you wanted between the courts, you would normally need a plural form or two separate nouns, for example:

• कोर्टों के बीच में = between the courts
• or एक कोर्ट और दूसरे कोर्ट के बीच में = between one court and another

So in your sentence, the meaning is clearly in the middle of the court.

In Hindi, many location expressions are built in layers.

Here is the structure:

• कोर्ट के = of the court
• बीच = middle
• में = in

So the full phrase is literally:

• in the middle of the court

Hindi often does this with noun-based location expressions:

• घर के बाहर = outside the house
• मेज़ के नीचे = under the table
• कमरे के अंदर = inside the room
• कोर्ट के बीच में = in the middle of the court

So yes, both parts are normal and needed.

है is the present tense form of to be for he/she/it/this/that and also for singular non-human things.

Since नेट is a singular thing, है is correct:

• नेट ... है = The net is ...

If the subject were plural, you would usually use हैं:

• नेट बीच में हैं = The nets are in the middle

नेट is usually treated as masculine in Hindi, especially in everyday usage, but in this sentence it does not affect much visibly.

Why it does not matter much here:

• The verb is है, which is the same for masculine and feminine singular in the present tense.
• There is no adjective here that changes form for gender.

So even if a learner does not know the gender yet, the sentence still looks the same:

• नेट कोर्ट के बीच में है।

They are loanwords, mainly from English, but they are very common in modern Hindi, especially in sports contexts.

Hindi often uses borrowed words for modern objects and sports terms:

• नेट = net
• कोर्ट = court
• मैच = match
• टीम = team

So this sentence sounds natural, especially when talking about tennis, badminton, volleyball, etc., depending on context.

A simple learner-friendly pronunciation guide:

• नेट = neṭ or roughly net
• कोर्ट = korṭ or roughly court
• के = kay
• बीच = beech
• में = mein / nasalized mayn
• है = hai / roughly heh or high depending on accent and how simplified you want it

A rough full pronunciation: neṭ korṭ kay beech mein hai

A couple of notes:

• ट in नेट and कोर्ट is a retroflex t, pronounced with the tongue curled back slightly.
• में has nasalization at the end.
• है is often pronounced lightly in normal speech.

Sometimes in casual speech you may hear shortened patterns, but the most standard and natural form here is:

नेट कोर्ट के बीच में है।

For learners, it is best to use बीच में as a fixed expression for in the middle.

So:

• best: कोर्ट के बीच में
• less standard for a beginner to imitate: कोर्ट के बीच

Just add नहीं before है:

• नेट कोर्ट के बीच में नहीं है।
• The net is not in the middle of the court.

This is a very common Hindi pattern:

• subject + location + नहीं है

A simple yes/no question is:

• क्या नेट कोर्ट के बीच में है?
• Is the net in the middle of the court?

Here क्या at the beginning marks the sentence as a yes/no question.

You may also hear the same words with question intonation in conversation, but for learners, using क्या is the clearest method.
