او خیلی دیر به خانه می آید.

A word-by-word breakdown looks like this:

• او = he / she
• خیلی = very
• دیر = late
• به = to
• خانه = home / house
• می آید = comes / is coming

So the sentence structure is literally something like:

he/she very late to home comes

That is normal Persian word order.

Persian often places the main verb at or near the end of the sentence. This is one of the biggest differences from English.

English:

• He comes home very late.

Persian:

• او خیلی دیر به خانه می آید.
• literally: He very late to home comes.

So for an English speaker, the final verb position may feel unusual, but it is completely standard in Persian.

می is a prefix used to mark the imperfective aspect. In many beginner contexts, this is taught as the marker for the present tense in sentences like this.

So:

• آید on its own is not how learners usually use the verb in normal modern speech
• می آید = comes / is coming

Depending on context, می‌آید can mean:

• comes (habitual)
• is coming (present, depending on context)
• sometimes even a near-future idea in the right context

In this sentence, it is most naturally understood as comes home very late.

Good question. In modern standard writing, this is very often written as:

• می‌آید

with a half-space (technically a zero-width non-joiner) between می and آید.

You may also see:

• می آید

with a regular space, especially in less formal typing or simplified materials.

So both may appear, but می‌آید is usually considered the more standard modern spelling.

It can mean either he or she.

Persian third-person singular pronouns do not show gender the way English does. So:

• او می آید = he comes or she comes

You only know the gender from context, if it is relevant at all.

Also, in everyday speech, او is often replaced by اون in informal spoken Persian.

به usually means to. It marks direction toward a place.

So:

• به خانه = to home / homeward
• more naturally in English: home

Persian often keeps this preposition where English might not. English says:

• He comes home

but Persian commonly says:

• او به خانه می‌آید
• literally: He to home comes

This is completely normal Persian usage.

It can mean both, depending on context, but in this sentence home is the better translation.

• خانه literally means house
• but very often it also means home

So به خانه می‌آید is best understood as:

• comes home

not just physically approaching a building.

خیلی دیر means very late.

• خیلی = very
• دیر = late

Together they describe how late the person comes home.

So:

• او به خانه می‌آید = He/She comes home
• او دیر به خانه می‌آید = He/She comes home late
• او خیلی دیر به خانه می‌آید = He/She comes home very late

A careful pronunciation would be approximately:

• u kheyli dir be khâne mi-âyad

A few notes:

• او sounds like u
• خیلی is roughly kheyli
• دیر is dir
• خانه is khâne
• می‌آید is roughly mi-âyad

In everyday spoken Persian, the verb is often pronounced more casually, and you may hear forms closer to:

• میاد = miyâd

So in colloquial speech, the whole sentence may sound more like:

• اون خیلی دیر به خونه میاد

It is fairly standard and neutral, but it leans a bit toward written or careful spoken Persian.

More formal/standard:

• او خیلی دیر به خانه می‌آید.

More conversational:

• اون خیلی دیر به خونه میاد.

Changes:

• او → اون
• خانه → خونه
• می‌آید → میاد

A learner should recognize both styles.

By itself, می‌آید can sometimes be interpreted in more than one way, depending on context.

It can mean:

• comes = habitual / regularly
• is coming = present action, in some contexts

But with خیلی دیر and به خانه, the most natural reading is usually habitual:

• He/She comes home very late

If you wanted to clearly describe something happening right now, context would usually make that obvious.

Yes, often it can.

Because the verb ending gives person information, Persian frequently drops the subject pronoun when it is understood from context.

So you could say:

• خیلی دیر به خانه می‌آید.

and it can still mean:

• He/She comes home very late.

However, keeping او is also correct, especially when you want to be explicit or contrast this person with someone else.

It comes from the verb آمدن = to come.

Important forms:

• infinitive: آمدن = to come
• present stem: آی
• third person singular present: می‌آید = he/she comes

This verb is a little tricky for beginners because the infinitive and present stem do not look exactly the same:

• آمدن → present stem آی

That kind of change is normal for some common Persian verbs.
