स्टेशन जाने से पहले मैं टिकट बैग में रखूँगी।

Because जाना changes to जाने before the postposition से.

• Basic infinitive: जाना = to go
• Oblique form before a postposition: जाने
• So जाने से पहले means before going

This is a very common pattern in Hindi:

• खाने से पहले = before eating
• सोने से पहले = before sleeping
• निकलने से पहले = before leaving

So स्टेशन जाने से पहले is the natural way to say before going to the station.

से पहले means before.

In this sentence, it attaches to the action जाने:

• जाने से पहले = before going

You can think of it as:

• X से पहले = before X

Examples:

• क्लास से पहले = before class
• खाने से पहले = before eating
• घर जाने से पहले = before going home

So here the whole first part sets the time: before going to the station.

With the verb जाना (to go), Hindi often uses the destination directly, without को.

So these are normal:

• घर जाना = to go home
• दिल्ली जाना = to go to Delhi
• स्टेशन जाना = to go to the station

Using स्टेशन को जाना would not be standard here.

If you want other shades of meaning, Hindi may use different postpositions:

• स्टेशन तक जाना = go up to/as far as the station
• स्टेशन पर जाना = go to the station / go over to the station, depending on context

But in the basic sense, स्टेशन जाना is perfectly natural.

Yes, it could often be omitted if the context already makes the subject clear.

Hindi frequently drops subject pronouns when they are understood. So both can work:

• मैं टिकट बैग में रखूँगी।
• टिकट बैग में रखूँगी।

The verb रखूँगी already tells you:

• first person singular = I
• feminine speaker = female I

So मैं is not always necessary, but it is very common to include it for clarity or emphasis.

Because this sentence is in the future, not in the perfective past.

Hindi uses ने mainly with many transitive verbs in perfective constructions, such as:

• मैंने टिकट रखा। = I put the ticket.

But in the future, you normally do not use ने:

• मैं टिकट रखूँगी। = I will put the ticket.

So:

• मैंने → common in perfective past
• मैं → normal here in the future

रखूँगी is the first person singular feminine future form of रखना (to put / to keep).

It tells us:

• I will …
• the speaker is female

Compare:

• रखूँगा = I will put/keep (male speaker)
• रखूँगी = I will put/keep (female speaker)

So if a man were speaking, the sentence would be:

• स्टेशन जाने से पहले मैं टिकट बैग में रखूँगा।

In this kind of sentence, the future verb agrees with the subject, not the object.

Here:

• subject = मैं
• object = टिकट
• location = बैग में

So the verb matches I, which is why we get रखूँगी if the speaker is female.

This is different from some perfective sentences in Hindi, where agreement can behave differently, especially when ने appears. But in this future sentence, the agreement is straightforward: it follows the subject.

Because टिकट is the direct object, and in Hindi inanimate direct objects often appear without को.

So:

• मैं टिकट रखूँगी। = natural
• मैं टिकट को रखूँगी। = possible only in a marked or contrastive sense, but not the normal choice here

Hindi often uses को more regularly with:

• animate/specific objects
• emphasis or contrast

In this sentence, plain टिकट is the normal form.

में means in / inside.

So:

• बैग = bag
• बैग में = in the bag

Since the ticket is being placed inside the bag, में is the correct postposition.

Compare:

• बैग में = in the bag
• बैग पर = on the bag
• बैग के पास = near the bag

So टिकट बैग में रखूँगी means the ticket will be placed inside the bag.

Not completely, but the given order is very natural.

Hindi usually prefers Subject–Object–Verb, and time expressions often come before the main clause:

• स्टेशन जाने से पहले = before going to the station
• मैं टिकट बैग में रखूँगी = I will put the ticket in the bag

You could also hear:

• स्टेशन जाने से पहले मैं बैग में टिकट रखूँगी।

That is also correct. The difference is mostly one of emphasis or flow, not basic meaning.

Hindi word order is more flexible than English, but the verb usually stays near the end.

Both are correct, but the focus can feel slightly different.

• टिकट बैग में रखूँगी: first mentions the ticket
• बैग में टिकट रखूँगी: first mentions the bag / location

In normal conversation, both can work. Hindi often shifts word order to highlight what is most important in the moment.

So this is more about emphasis than grammar.

It can suggest either, depending on context.

रखना is a broad verb that often means:

• to put
• to place
• to keep

In this sentence, it probably means something like:

• I’ll put the ticket in the bag or
• I’ll keep the ticket in the bag

English may choose different verbs depending on context, but Hindi often uses रखना in all of these situations.

Yes, जाने के पहले is also heard and understood, and in many contexts it sounds natural. But जाने से पहले is a very common and standard pattern.

So both may occur:

• स्टेशन जाने से पहले
• स्टेशन जाने के पहले

For learners, verb + ने/ने? Actually the safest pattern to remember here is:

• खाने से पहले
• जाने से पहले
• सोने से पहले

That pattern is extremely useful and very common.
