स्टेशन जाने से पहले हमने टिकट देखा।

A helpful breakdown is:

• स्टेशन = station
• जाने = going / to go
• से पहले = before
• हमने = we + ने
• टिकट = ticket
• देखा = saw / looked at / checked

So the structure is basically:

[station going before] [we-ERG] [ticket] [saw]

This is very normal Hindi structure: a time clause first, then the main clause, with the verb at the end.

Because Hindi often uses ने with the subject of a transitive verb in the perfective past.

Here, देखा is the perfective form of देखना and it is transitive because something is being seen: टिकट.

So:

• हम = we
• हमने = we + ergative marker ने

This is a very common pattern in Hindi:

• मैंने खाना खाया। = I ate food.
• उसने किताब पढ़ी। = He/she read the book.
• हमने टिकट देखा। = We saw/checked the ticket.

Because जाना changes to जाने before a postposition such as से.

This form is often called the oblique infinitive. A very common pattern is:

• करने से पहले = before doing
• खाने से पहले = before eating
• जाने से पहले = before going

So:

• जाना = to go
• जाने से पहले = before going

You cannot normally say जाना से पहले here.

से पहले is the standard Hindi way to say before after a verbal expression or noun.

In this sentence:

• स्टेशन जाने से पहले = before going to the station

You can think of the full pattern as:

[verb in -ने form] + से पहले = before doing X

Examples:

• सोने से पहले = before sleeping
• घर जाने से पहले = before going home
• स्टेशन जाने से पहले = before going to the station

This is one of the most useful time-clause patterns in Hindi.

With verbs of motion like जाना, Hindi very often uses the destination directly, without a separate marker like English to.

So all of these are natural:

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

So स्टेशन जाने already means going to the station. Hindi does not need an extra word there.

By default, it is understood to be the same subject as in the main clause: we.

So the natural interpretation is:

Before going to the station, we...

Hindi often leaves the subject of this kind of non-finite clause unstated when it is obvious from context.

If you wanted to make a different subject explicit, Hindi would usually show that more clearly.

Because Hindi normally follows Subject–Object–Verb word order, and the main verb usually comes last.

Here the sentence is:

• स्टेशन जाने से पहले = time expression
• हमने = subject
• टिकट = object
• देखा = verb

So ending with the verb is exactly what you would expect in Hindi.

Because in this kind of sentence, when the subject takes ने, the verb often agrees with the direct object if that object has no को.

Here the direct object is टिकट, and in this sentence it is being treated as masculine singular, so the verb appears as देखा.

A useful rule of thumb:

• perfective transitive clause
• subject marked with ने
• object has no को
• verb agrees with the object

One extra note: with some borrowed nouns such as टिकट, gender can vary by speaker or context. But in this sentence, the form देखा shows that the noun is being treated as masculine singular here.

Yes, in normal learning terms, you can treat देखा here as a simple past / perfective form.

So the main event is completed:

• हमने टिकट देखा। = We saw / looked at / checked the ticket.

Hindi is often better described in terms of aspect as well as tense, and देखा is specifically a perfective form. But for most learners, past action completed is the right idea here.

It can mean any of those depending on context.

With टिकट, the most natural English idea is often:

• looked at the ticket
• checked the ticket

A very literal translation saw the ticket is possible, but in real context this sentence often suggests that they examined or checked it before leaving.

So देखना is broader than just physically seeing something. It can also mean look at, check, or inspect, depending on the situation.

The given order is very natural, but Hindi does allow some flexibility.

For example, this is also possible:

• हमने स्टेशन जाने से पहले टिकट देखा।

Both versions are understandable. The original version puts the before going to the station part first, which gives it a nice natural emphasis as a time setting.

So Hindi word order is flexible, but:

• the verb usually stays near the end
• the original order sounds very normal and natural
