जेब में पैसा है।

में is the postposition meaning in / inside.

So:

• जेब = pocket
• में = in

Together, जेब में means in the pocket or in a pocket.

Hindi uses postpositions, not prepositions. That means the equivalent of English in comes after the noun, not before it.

Because Hindi and English organize these words differently.

• English uses a preposition: in the pocket
• Hindi uses a postposition: जेब में

So in Hindi, the location noun comes first, and the relational word comes after it.

This is one of the most common patterns in Hindi:

• घर में = in the house
• बैग में = in the bag
• जेब में = in the pocket

Hindi usually does not require articles like English a/an/the.

So जेब can mean:

• a pocket
• the pocket
• pocket

Which one sounds best in English depends on context.

That is very normal in Hindi. The sentence leaves that detail unstated unless it is important.

Hindi often puts the location first, then the thing being talked about, and then the verb है at the end.

So the structure here is:

• जेब में = in the pocket
• पैसा = money
• है = is

Literally, it is something like In the pocket money is.

This is a very common Hindi pattern for existence or location:

• कमरे में आदमी है। = There is a man in the room.
• बैग में किताब है। = There is a book in the bag.

Yes, you can.

Both are grammatical, but the emphasis changes a little:

• जेब में पैसा है। = focuses first on the location; very natural for There is money in the pocket.
• पैसा जेब में है। = focuses more on money; closer to The money is in the pocket.

So the original sentence is a very natural choice when you are introducing the fact that money is present in that location.

Because पैसा is grammatically singular here.

In this sentence, पैसा means money as a mass noun or singular idea, so Hindi uses है.

Compare:

• जेब में पैसा है। = There is money in the pocket.
• जेब में पैसे हैं। = There is money / there are coins / there are rupees in the pocket.

The second version uses पैसे and हैं, which are plural.

Good question. In modern Hindi:

• पैसा can mean money in a general or mass sense
• पैसे is plural and often means money / coins / rupees / funds

So:

• जेब में पैसा है। = There is money in the pocket.
• जेब में पैसे हैं। = There is money in the pocket / There are some coins or rupees in the pocket.

In real speech, पैसे is extremely common when people mean money in a practical sense.

Not by itself.

जेब just means pocket. The sentence does not explicitly say whose pocket it is.

Depending on context, English might translate it as:

• There is money in the pocket
• There is money in a pocket
• sometimes even There is money in my pocket, if the situation already makes that clear

If you want to say my pocket clearly, you would say:

• मेरी जेब में पैसा है। = There is money in my pocket.

Hindi usually does not need a dummy subject like English there.

English says:

• There is money in the pocket.

Hindi simply says:

• जेब में पैसा है।

The idea of existence is expressed by the noun plus है in context. Hindi often just states the location and the thing that exists there.

So the sentence is literally simple, but it naturally carries the meaning there is.

Here जेब is in the direct form, because feminine nouns ending in a consonant or certain other shapes often do not visibly change before postpositions.

With many Hindi nouns, a postposition like में requires the oblique form. But for जेब, the form looks the same:

• direct: जेब
• oblique: जेब

So learners do not see any change here, even though grammatically a postposition is being used.

A natural pronunciation is roughly:

jeb mein paisā hai

A few notes:

• जेब sounds like jabe without a strong final vowel: jeb
• में has a nasalized vowel, roughly mein
• पैसा sounds like pai-saa
• है in normal speech often sounds like hai

So altogether: jeb mein paisā hai

Yes. Just change the final verb.

Examples:

• जेब में पैसा था। = There was money in the pocket.
• जेब में पैसा होगा। = There will be money in the pocket. / There must be money in the pocket, depending on context.

The rest of the sentence stays the same, and the tense is shown mainly by the verb at the end.
