صديقي يذهب الى المقهى وحده في المساء.

A careful MSA pronunciation would be:

ṣadīqī yadhhabu ilā al-maqhā waḥdahu fī al-masāʾi

A few sound notes:

• ṣ in ṣadīqī is an emphatic s
• dh in yadhhabu sounds like th in this
• q in al-maqhā is a deep k sound made farther back in the throat
• ḥ is a stronger, breathier h
• the final ʾ in masāʾ is a glottal stop

In normal pause at the end of the sentence, many speakers would stop at المساء without clearly pronouncing the final case vowel.

Because صديق means friend, and the suffix -ي means my.

So:

• صديق = friend
• صديقي = my friend

This is a very common Arabic pattern. Instead of using a separate word for my, Arabic often attaches a pronoun suffix directly to the noun.

Other examples:

• كتابي = my book
• بيتي = my house

So صديقي is literally friend-my.

يذهب is the imperfect (non-past) form of the verb ذهب = to go.

Here, يذهب means:

• he goes
• or, depending on context, he is going

In this sentence, it is most naturally understood as a habitual or regular action: he goes.

What the form tells you:

• يـ at the beginning often marks a 3rd person masculine singular imperfect verb
• so يذهب = he goes

If the subject were feminine, it would be تذهب.

Because Arabic verbs already contain subject information.

يذهب by itself already means he goes.

So Arabic does not need a separate pronoun here. The noun صديقي names who that he is:

• صديقي = my friend
• يذهب = he goes

Together: My friend goes

If you added هو here, it would usually be for emphasis, not because grammar requires it.

Arabic allows more than one natural word order.

This sentence starts with the noun:

صديقي يذهب...
My friend goes...

You could also say:

يذهب صديقي...

Both are possible, but they feel slightly different.

A simple way to think about it:

• صديقي يذهب... puts my friend first as the topic
• يذهب صديقي... starts more directly with the action

For learners, both are worth recognizing. Arabic is more flexible than English in word order.

Yes. In standard spelling, it is إلى.

It means to.

So:

• إلى المقهى = to the café

You will often see الى without the hamza in casual typing, texting, or informal online writing, but the standard MSA spelling is:

إلى

So the sentence is more formally written as:

صديقي يذهب إلى المقهى وحده في المساء.

المقهى is pronounced roughly:

al-maqhā

The final ى is called alif maqṣūrah. It represents a final long ā sound.

So even though it looks different from a regular ا, it still gives an ā sound here.

Also note:

• الـ = the
• مقهى = café / coffeehouse
• المقهى = the café

And because م is a moon letter, the ل in الـ is pronounced clearly:

• al-maqhā, not a doubled m

وحده means alone or by himself.

It is made from:

• وحد = alone / by oneself
• ـه = him / his

So وحده literally means something like alone-him, which idiomatically means by himself.

In this sentence, it describes how the friend goes to the café:

• يذهب ... وحده = he goes ... alone

Grammatically, this is an adverb-like expression describing the state or manner of the subject.

A fully vocalized form is:

وحدَهُ
waḥdahu

في means in, and المساء means the evening.

So:

• في المساء = in the evening

This phrase tells you when the action happens.

Arabic often uses this kind of prepositional phrase for time expressions:

• في الصباح = in the morning
• في الليل = at night
• في المساء = in the evening

The definite article الـ here is normal, so المساء is the evening.

Because Arabic often expresses times of day as definite nouns:

• الصباح = the morning
• المساء = the evening
• الليل = the night

So في المساء is the normal way to say in the evening.

English sometimes uses a bare expression like at night, but Arabic often prefers the definite noun with الـ in these time phrases.

In normal Arabic writing, short vowels and many case endings are usually not written.

So the sentence appears as:

صديقي يذهب إلى المقهى وحده في المساء

But in a more fully vocalized form, you could write:

صديقي يذهبُ إلى المقهى وحدَهُ في المساءِ

A few things to notice:

• يذهبُ has a final -u
• وحدَهُ shows the accusative/adverbial form
• المساءِ is after في, so it is genitive in careful reading

Some words in this sentence do not show an obvious spoken case difference:

• صديقي has the my suffix, which hides the usual case contrast
• المقهى ends in alif maqṣūrah, so the case ending is not visibly pronounced in the normal way

So yes, the grammar is there, but everyday writing usually leaves those endings unstated.
