او هم بلیت قطار را خواهد خرید، چون فردا سفر دارد.

Yes. او is gender-neutral, so it can mean he or she depending on context. Persian personal pronouns do not normally show gender.

Here هم means also / too, and its position shows what it is adding emphasis to.

• او هم ... = he/she too ...
• So the meaning is: He/She will also buy...

If you moved هم, the focus could change. For example, placing it near another word might suggest the ticket too or will also buy instead.

را marks the direct object. It usually appears with a specific or definite object.

So:

• بلیت قطار را = the train ticket / a particular train ticket

A useful rule:

• the whole noun phrase comes first
• را comes after that whole phrase

So Persian says:

• بلیت قطار را
  not
• بلیت را قطار

Because بلیت قطار is one complete noun phrase: train ticket.
The object marker را comes after the entire object, not after just the first noun.

So the structure is:

• بلیت قطار = train ticket
• بلیت قطار را = the train ticket as the direct object

Yes, in pronunciation there is normally an ezafe link:

• بلیتِ قطار

In normal Persian writing, short vowels are usually not written, so you often just see:

• بلیت قطار

But learners should understand it as pronounced roughly like belit-e qatar.

This is the formal future tense.

It is built with:

• a future form of خواستن
• plus the past stem of the main verb

Here:

• خواهد = will (3rd person singular)
• خرید = past stem of خریدن (to buy)

So:

• خواهد خرید = he/she will buy

This pattern is common in formal written Persian:

• خواهم رفت = I will go
• خواهی دید = you will see
• خواهد خرید = he/she will buy

It is correct, but it sounds more formal or written. In everyday spoken Persian, people often use the present tense to talk about the future if the time is clear from context.

So in speech, you may often hear something like:

• فردا بلیت قطار را می‌خرد

Even though that is present in form, it can mean will buy tomorrow because فردا already makes the future clear.

Because Persian usually follows Subject–Object–Verb order.

In this sentence:

• او = subject
• بلیت قطار را = object
• خواهد خرید = verb

So the main clause is:

• او هم بلیت قطار را خواهد خرید

This verb-final order is one of the biggest differences from English.

The same tendency appears in the clause after چون:

• فردا سفر دارد
• literally: tomorrow a trip has

چون here means because / since.

So:

• چون فردا سفر دارد = because he/she has a trip tomorrow

It introduces the reason for the action in the main clause.

Be aware that چون can also have other meanings in other contexts, but here it is simply because.

سفر دارد literally means has a trip/journey, but in natural English it often corresponds to:

• has a trip tomorrow
• is traveling tomorrow
• has to travel tomorrow

This is a very natural Persian way to express that someone has travel planned.

So the sentence is not talking about travel in a general sense; it suggests a specific upcoming trip.

Yes, very often. Persian commonly drops subject pronouns when the meaning is clear from context.

So you could say:

• هم بلیت قطار را خواهد خرید، چون فردا سفر دارد.

or more naturally without هم at the start unless the context supports it:

• بلیت قطار را خواهد خرید، چون فردا سفر دارد.

However, keeping او can help with clarity or emphasis, especially in written language.

It depends on context, but را usually makes the object feel specific. So in many contexts, English will translate it as:

• the train ticket
• or a certain train ticket

Without را, the noun could sound less specific.

So:

• بلیت قطار را suggests a specific ticket
• بلیت قطار without را would be less clearly specific

A simple learner-friendly pronunciation is:

• u ham belit-e qatar râ xâhad xarid, چون fardâ safar dârad

A smoother version in Latin letters:

• u ham belit-e qatar râ khâhad kharid, chun fardâ safar dârad

Very roughly:

• oo ham beh-leet-e gha-târ râ khâ-had kha-reed, choon far-dâ sa-far dâ-rad

Exact pronunciation varies a bit by accent, but this is a good starting point.
