शाम को मैं आपके साथ बाज़ार जाऊँगी।

In this sentence, को marks the time when something happens.

So शाम को means in the evening / this evening.

This use of को is very common with time expressions in Hindi, for example:

• सोमवार को = on Monday
• रात को = at night
• शाम को = in the evening

It is not the object marker here. It is just part of the time expression.

Hindi normally puts the main verb at the end of the clause.

A natural breakdown of the sentence is:

• शाम को = time
• मैं = subject
• आपके साथ = with you
• बाज़ार = destination
• जाऊँगी = will go

So the overall pattern is very typical Hindi word order: time + subject + other information + verb

English usually places the verb earlier, but Hindi strongly prefers it at the end.

It means with you.

More literally:

• आप = you, polite/respectful
• के साथ = with

So:

• मेरे साथ = with me
• तुम्हारे साथ = with you
• उसके साथ = with him/her
• आपके साथ = with you (polite)

A good way to learn it is to treat के साथ as a set expression meaning with.

Because Hindi uses postpositions, and many of them require a special linked form before them.

With साथ, the usual expression is के साथ. So pronouns appear like this:

• मेरे साथ
• तुम्हारे साथ
• आपके साथ

So आपके साथ is the normal grammatical form for with you.

It does not mean possession here. Even though आपके can sometimes mean your, in this sentence it is simply part of the postpositional phrase के साथ.

Yes. आप is the polite or respectful word for you.

So this sentence sounds respectful, appropriate for:

• someone older
• someone you do not know well
• a teacher, customer, guest, etc.

If you were talking to a friend, you might say:

• तुम्हारे साथ instead of आपके साथ

So the choice of आप tells you something about the relationship between the speaker and the listener.

Because the speaker is female.

With मैं, the future form of जाना changes according to the speaker’s gender:

• मैं जाऊँगा = I will go — said by a male
• मैं जाऊँगी = I will go — said by a female

So जाऊँगी tells you that the speaker is a woman or girl.

The dictionary form is जाना = to go.

The future first-person singular feminine form is जाऊँगी.

You can think of it roughly as:

• जा- = go
• -ऊँ- = future/first-person part
• -गी = feminine marker

Compare:

• मैं जाऊँगा = I will go — masculine
• मैं जाऊँगी = I will go — feminine

You do not need to build it manually every time at first; it is best to memorize जाऊँगा / जाऊँगी as common future forms of जाना.

With verbs like जाना and आना, Hindi often uses the destination without any extra postposition.

So these are normal:

• घर जाना = to go home
• स्कूल जाना = to go to school
• बाज़ार जाना = to go to the market

If you say बाज़ार में, that usually means in the market, not to the market.

So in this sentence, बाज़ार जाऊँगी naturally means will go to the market.

Yes, often it can.

Hindi frequently drops pronouns when the meaning is clear from context. So this is also natural:

• शाम को आपके साथ बाज़ार जाऊँगी।

Because जाऊँगी already tells us the speaker is I and female, the subject can be understood.

However, keeping मैं can make the sentence clearer or slightly more emphatic.

Yes, to some extent. Hindi word order is flexible, although the verb usually stays near the end.

For example, these are all possible in the right context:

• मैं शाम को आपके साथ बाज़ार जाऊँगी।
• शाम को मैं आपके साथ बाज़ार जाऊँगी।
• मैं आपके साथ शाम को बाज़ार जाऊँगी।

The meaning stays very similar, but the focus or emphasis can shift a little.

The version you were given is very natural and neutral.

A rough pronunciation is:

jaa-oong-ee

A few helpful points:

• जा sounds like jaa
• ऊँ has a nasal sound
• गी sounds like gee

So say it smoothly as one word: जा-ऊँ-गी

Do not worry if your nasalization is not perfect at first; learners are usually understood as long as the overall shape of the word is clear.

Both spellings are common.

• बाज़ार uses ज़, which shows a z sound
• बाजार leaves out the dot, which is also very common in everyday writing

In modern Hindi, many people write words with or without the dot, especially in informal contexts. For a learner, the important thing is that both refer to the same word: market.
