في الساعة العاشرة اعود من الجامعة الى البيت.

Literally, it means in the tenth hour, but in normal English it means at ten o’clock.

Arabic often tells time with:

• الساعة = the hour / o’clock
• an ordinal number after it

So:

• الساعة الأولى = one o’clock
• الساعة الثانية = two o’clock
• الساعة العاشرة = ten o’clock

With في, the whole phrase في الساعة العاشرة means at ten o’clock.

Because الساعة is a feminine noun, and the ordinal number has to agree with it.

So:

• الساعة is feminine
• therefore العاشرة is the feminine form of tenth

That is why Arabic says الساعة العاشرة for ten o’clock.

Yes. In this sentence, في الساعة العاشرة is a normal way to say at ten o’clock.

You may also see:

• عند الساعة العاشرة = at ten o’clock

That can sound a bit more formal or specific.

If you want to say around ten o’clock, you would usually say something like:

• حوالي الساعة العاشرة

So في الساعة العاشرة normally suggests a time at ten, not approximately ten.

Because the verb itself already tells you the subject.

أعود means I return / I come back.
The prefix أ- marks first person singular in the present tense.

So:

• أعود = I return
• نعود = we return
• تعود = you return / she returns
• يعود = he returns

You can add أنا if you want emphasis:

• أنا أعود من الجامعة إلى البيت

But it is not necessary.

In standard written Arabic, yes: أعود is the correct spelling.

The initial sound is a hamza, so it should normally be written on an alif:

• correct standard spelling: أعود
• casual simplified typing: اعود

Learners should write أعود in careful Modern Standard Arabic.

In Arabic, the present tense often covers several meanings that English separates.

أعود can mean:

• I return
• I am returning (depending on context)
• I usually return
• sometimes a near-future meaning, depending on the situation

In this sentence, the most natural reading is a habitual action or routine:

• At ten o’clock, I return from the university to the house/home.

So it often feels like I come home from the university at ten o’clock.

They show movement from one place to another:

• من الجامعة = from the university
• إلى البيت = to the house / home

This is a very common Arabic pattern:

• من ... إلى ... = from ... to ...

So the sentence describes a movement path:

from the university → to home

Because Arabic often uses the definite article where English may not.

Here:

• الجامعة = the university
• البيت literally = the house

But in many contexts, البيت naturally means home.

So Arabic commonly says:

• أذهب إلى البيت = I go home
• أعود إلى البيت = I return home

Even though English usually drops the in go home, Arabic normally keeps الـ.

You can say إلى بيتي, but it is slightly different.

• إلى البيت = to the house / home
• إلى بيتي = to my house / to my home

In many everyday situations, إلى البيت is the normal idiomatic way to say home.
If you want to stress possession, then إلى بيتي is clearer.

Yes. Arabic word order is flexible.

The given sentence begins with the time phrase:

• في الساعة العاشرة أعود من الجامعة إلى البيت

This gives early emphasis to when the action happens.

You could also say:

• أعود من الجامعة إلى البيت في الساعة العاشرة

That is also correct. It just sounds a little different in emphasis. The meaning stays basically the same.

A fully vocalized version would be:

فِي السَّاعَةِ الْعَاشِرَةِ أَعُودُ مِنَ الْجَامِعَةِ إِلَى الْبَيْتِ.

This can help you see the grammar more clearly.

For example:

• السَّاعَةِ is after في, so it is in the genitive
• الْعَاشِرَةِ matches السَّاعَةِ
• الْجَامِعَةِ is after من
• الْبَيْتِ is after إلى

In normal Arabic writing, these final short vowels are usually not written.

It is pronounced as-sāʿa, not al-sāʿa.

That is because س is a sun letter. With sun letters, the l sound of الـ is absorbed into the next consonant.

So:

• الساعة → as-sāʿa

But:

• الجامعة → al-jāmiʿa
• البيت → al-bayt

because ج and ب are moon letters, so the l sound is pronounced normally.

A very natural English understanding is:

• At ten o’clock, I return home from the university.
• I come home from the university at ten o’clock.

The Arabic is slightly more literal if translated word-for-word:

• At ten o’clock I return from the university to the البيت/home.

But in natural English, return home is usually the best way to understand it.
