वह बच्ची माँ के साथ बाज़ार जा रही है।

वह can mean both he/she/it and that, depending on context.

In this sentence, वह बच्ची most naturally means that girl or the girl. If the context is already clear, it can also feel close to she.

The verb helps too: जा रही है is feminine singular, so we know the person being talked about is female.

बच्चा is the masculine form meaning child/boy, while बच्ची is the feminine form meaning girl child/little girl.

Because the sentence is about a female child, Hindi uses बच्ची.

You can also notice that the verb matches this feminine subject:

• बच्चा जा रहा है = a boy/child is going
• बच्ची जा रही है = a girl is going

माँ के साथ means with mother / with her mother.

The postposition के साथ means with. So the structure is:

• माँ = mother
• के साथ = with

Together: माँ के साथ = with mother

In Hindi, words like with, in, on, to, and from are usually expressed with postpositions, which come after the noun, not before it.

So English with mother becomes:

• माँ के साथ

Here, के साथ works as a unit meaning with.

A learner often expects का/की/के to always mean possession, but in expressions like के साथ, it is part of a fixed postpositional phrase.

Hindi often does not need a separate word for to when talking about going to a place.

So:

• बाज़ार जा रही है = is going to the market

This is very natural in Hindi. With destinations, Hindi often just uses the place name directly before the verb of motion.

जा रही है is the present continuous/progressive form, meaning is going.

It is made of:

• जा = from the verb जाना = to go
• रही = progressive part, agreeing with a feminine singular subject
• है = is

So:

• जा रही है = is going

This is the standard way to say that someone is in the process of going somewhere.

Because the subject is feminine singular: बच्ची.

In Hindi, the participle in this kind of verb phrase agrees with the subject:

• masculine singular: रहा
• feminine singular: रही
• plural / respectful masculine mixed: रहे

So:

• वह बच्चा जा रहा है = that boy is going
• वह बच्ची जा रही है = that girl is going

This is an important difference:

• जा रही है = is going
  This describes an action happening right now or around now.

• जाती है = goes / usually goes
  This describes a habitual action.

So:

• वह बच्ची बाज़ार जा रही है = the girl is going to the market
• वह बच्ची बाज़ार जाती है = the girl goes to the market / usually goes to the market

Yes, this is normal Hindi word order.

Hindi usually prefers verb-final order. A simple pattern is:

subject + other information + main verb

So here:

• वह बच्ची = subject
• माँ के साथ = with mother
• बाज़ार = market
• जा रही है = is going

English puts the verb earlier, but Hindi typically saves it for the end.

No, Hindi does not have articles exactly like English a/an and the.

That means बच्ची by itself could mean:

• a girl
• the girl

The exact meaning comes from context.

In this sentence, वह makes it more specific, so वह बच्ची often feels like that girl or the girl.

Not literally and automatically.

माँ के साथ literally means with mother or with the mother, but in context it often naturally implies with her mother.

If you want to make possession explicit, you could say:

• अपनी माँ के साथ = with her own mother
• उसकी माँ के साथ = with her mother

Still, in many everyday sentences, Hindi leaves this understood from context.

A couple of pronunciation points:

• माँ has a long aa sound plus nasalization. It sounds roughly like maa, but with a nasal tone.
• बाज़ार is pronounced roughly baa-zaar.
• The letter ज़ has a z sound, unlike ज, which is more like j in jam.

So:

• माँ ≈ maã
• बाज़ार ≈ baazaar

These are useful details because both nasalization and the ज़ sound matter in careful pronunciation.
