في المساء أشاهد فيلما مع صديقتي ونسمع موسيقى بعده.

A fully vocalized version is:

في المساءِ أُشاهِدُ فيلمًا مع صديقتي ونَسْمَعُ موسيقى بعدَهُ.

A rough pronunciation is:

fi l-masā’i ushāhidu fīlman maʿa ṣadīqatī wa-nasmaʿu mūsīqā baʿdahu

Notes:

• أشاهد is pronounced ushāhidu
• صديقتي is ṣadīqatī
• بعده is baʿdahu

في المساء means in the evening.

Arabic often puts a time expression at the beginning of the sentence to set the scene first. So this structure is very natural:

• في المساء أشاهد... = In the evening, I watch...

You could also say:

• أشاهد فيلمًا في المساء = I watch a film in the evening

Both are correct, but starting with في المساء gives the time frame right away.

أشاهد is a present-tense verb meaning I watch or I am watching, depending on context.

The prefix أ- tells you the subject is I.

So:

• أشاهد = I watch / I am watching
• نشاهد = we watch
• تشاهد = you watch / she watches
• يشاهد = he watches

In this sentence, the meaning is probably habitual or general: I watch.

Yes. In fully vocalized Arabic, it is فيلمًا.

It is the direct object of أشاهد, so it is in the accusative case.

That is why it takes tanwīn fatḥ:

• فيلمٌ = a film (subject form)
• فيلمًا = a film (object form)

In normal everyday Arabic writing, short vowels are usually omitted, so you may simply see فيلما in plain text.

Also, Arabic does not use a separate word for a/an, so فيلمًا already means a film.

مع صديقتي means with my female friend.

Breakdown:

• مع = with
• صديقة = female friend
• صديقتي = my female friend

The -ي at the end means my.

Also notice this important spelling point:

• صديقة
• but with a suffix: صديقتي

The ة becomes a pronounced t sound before endings like -ي.

It can mean either, depending on context.

Literally, صديقتي means my female friend. In some contexts, it can also mean my girlfriend. Arabic often relies on context to make the difference clear.

So by itself, صديقتي does not automatically mean a romantic partner. It may simply mean my friend who is female.

Because the subject changes.

At first, the speaker says:

• أشاهد = I watch

Then the sentence says:

• مع صديقتي = with my female friend

After that, the next action is done by both people together:

• نسمع = we hear / we listen

So the meaning is:

• I watch a film with my friend, and then we listen to music after it.

If the speaker meant that only they listen, it would be:

• وأسمع موسيقى بعده = and I listen to music after it

Because Arabic verbs already show the subject.

• نسمع already means we hear / we listen
• So نحن is not necessary

Arabic often leaves subject pronouns out unless there is special emphasis or contrast.

Compare:

• نسمع موسيقى = We listen to music
• نحن نسمع موسيقى = We listen to music with extra emphasis, like we specifically

Literally, نسمع موسيقى means we hear music.

In careful or formal Modern Standard Arabic, listen to is often expressed as:

• نستمع إلى موسيقى = we listen to music

So:

• نسمع موسيقى = we hear music / we listen to music in a looser, simpler way
• نستمع إلى موسيقى = we listen to music more precisely

In learning materials, نسمع موسيقى is often used because it is simpler and still easy to understand.

بعده means after it or after him, depending on context.

Here it means after it, and -ه refers to فيلم (film).

Breakdown:

• بعد = after
• -ه = him / it

Since فيلم is grammatically masculine singular, the pronoun is -ه.

So:

• بعده = after it = after the film

If the word were feminine, you would use -ها instead:

• بعدها = after her / after it (feminine)

Yes. موسيقى here means music in a general sense.

Arabic often uses a bare noun for an indefinite or general meaning:

• موسيقى = music
• الموسيقى = the music

So in this sentence, نسمع موسيقى means we listen to music, not we listen to the music.

Also, موسيقى is the object of نسمع, but its case ending is not visible in normal spelling because of the way the word ends.
