स्कूल के बाद मैं घर आऊँगी।

के बाद means after.

In Hindi, this is a postposition, not a preposition. That means it comes after the noun, not before it.

• स्कूल के बाद = after school
• literally: school + of/related-to + after

The के is part of the structure used before बाद. You learn this as a fixed pattern:

• X के बाद = after X
• X के पहले / X से पहले = before X

So स्कूल के बाद is the natural way to say after school.

Both आना (to come) and जाना (to go) can be possible in different contexts.

• मैं घर आऊँगी = I will come home
• मैं घर जाऊँगी = I will go home

Hindi often chooses आना or जाना based on point of view, just like English sometimes does.

If the speaker is talking from the perspective of home as the destination, आना can sound natural:

• मैं घर आऊँगी = I’ll come home

If the focus is simply on leaving for home from another place, जाना can also work:

• मैं घर जाऊँगी = I’ll go home

In many everyday situations, both are understandable, but this sentence uses आना to match the idea come home.

आऊँगी is the future tense form of आना (to come) for:

• first person singular = I
• feminine speaker

So:

• मैं आऊँगा = I will come (said by a male)
• मैं आऊँगी = I will come (said by a female)

In this sentence:

• मैं घर आऊँगी = I will come home

In Hindi, verbs often agree with the speaker or subject in gender and number, especially in forms like the future.

So if the speaker is female:

• मैं आऊँगी

If the speaker is male:

• मैं आऊँगा

This is very normal in Hindi, even though English does not do this. English says I will come no matter who is speaking, but Hindi changes the verb ending.

Yes, very often.

Hindi frequently drops subject pronouns when they are already clear from context or from the verb ending.

So both of these can work:

• स्कूल के बाद मैं घर आऊँगी।
• स्कूल के बाद घर आऊँगी।

Because आऊँगी already tells you the speaker is:

• I
• feminine
• future

Still, मैं is often included for clarity, emphasis, or natural flow.

In Hindi, घर often works without a postposition when it means home as a destination.

So:

• मैं घर आऊँगी = I will come home
• वह घर गया = He went home

This is similar to English, where we also usually say go home, not go to home.

If you were talking about a different kind of place, Hindi often would use a postposition such as में, पर, or को, depending on the meaning. But घर is special and very commonly appears without one in this kind of sentence.

The sentence follows normal Hindi word order:

• स्कूल के बाद = after school
• मैं = I
• घर = home
• आऊँगी = will come

So the structure is roughly:

time expression + subject + place + verb

Hindi usually puts the verb at the end, unlike English.

Compare:

• English: After school, I will come home.
• Hindi: स्कूल के बाद मैं घर आऊँगी।

That final-verb pattern is one of the most important differences between Hindi and English.

A learner-friendly pronunciation is roughly:

aa-oong-gee

More carefully:

• आ = long aa
• ऊँ = oo with nasalization
• गी = gee

So the middle part has a nasal sound:

• आऊँगी
• roughly: aa-ũ-gii

The ँ mark shows nasalization. You do not pronounce it as a full separate consonant; instead, the vowel gets a nasal quality.

Yes, स्कूल is a borrowing from English school, and it is completely normal in modern Hindi.

Hindi uses many loanwords in everyday speech, especially for things like:

• school
• bus
• train
• hospital

So स्कूल के बाद is a very natural everyday phrase.

There is no problem with using स्कूल in a Hindi sentence.

Usually, घर here is understood as home, so the most natural translation is:

• After school, I will come home.

But घर can also mean house/home depending on context. If the context is about coming to a particular house, the meaning could shift slightly.

Still, in ordinary conversation, मैं घर आऊँगी most commonly means I’ll come home.
