اليوم عندي درس، ولازم ادرس بالبيت بالليل.

A rough Levantine pronunciation is:

il-yōm ʿindī dars, w-lāzem edros bil-bēt bil-lēl.

A few notes:

• اليوم → il-yōm
• عندي → ʿindī
• درس → dars
• ولازم → w-lāzem
• ادرس → often edros in Levantine pronunciation, though this can vary by region
• بالبيت → bil-bēt
• بالليل → bil-lēl

Regional pronunciation varies, so you may hear slightly different vowels.

Yes. In this sentence, اليوم means today.

Even though the word is literally related to the day, in both Standard Arabic and everyday Levantine it is very commonly used to mean today.

In Arabic, possession is often expressed differently from English.

عندي is made of:

• عند = at / with
• ـي = my / me

So عندي literally means something like with me or at me, but in natural English we translate it as I have.

So:

• عندي درس = I have a lesson / class

This pattern is very common:

• عندك = you have
• عنده = he has
• عندها = she has

Here, درس most naturally means a lesson or a class.

Depending on context, درس can refer to:

• a school lesson
• a class session
• something you need to study

In this sentence, عندي درس most likely means I have a class or I have a lesson today.

If you wanted to say I have homework, you would usually use a different word, such as واجب.

لازم means must, have to, or need to.

In Levantine, it is extremely common and very useful. It is followed by a verb:

• لازم ادرس = I have to study
• لازم روح = I have to go
• لازم نشتغل = we have to work

In your sentence, ولازم is just:

• و = and
• لازم = must / have to

So ولازم ادرس = and I have to study.

This is a very common Levantine grammar point.

In everyday Levantine, the present tense often uses بـ:

• بدرس = I study / I am studying / I study عادةً

But after words like لازم, the verb is usually used without بـ:

• لازم ادرس = I have to study
• not usually لازم بدرس

So the sentence uses the normal Levantine pattern.

In informal Arabic writing, especially texting and casual writing, people often leave out the hamza spelling.

So:

• أدرس
• ادرس

can represent the same word in casual writing.

This is very normal in dialect writing. People often spell things more loosely than in formal Standard Arabic.

No. You do not need to say أنا here.

Arabic verbs already include the subject, so ادرس already tells you the subject is I.

That means:

• لازم ادرس = I have to study

If you say أنا لازم ادرس, that is also possible, but أنا adds emphasis, like:

• I have to study

So in normal speech, leaving out أنا is completely natural.

بالبيت is:

• بـ = in / at
• البيت = the house / home

So literally it means in the house, but very often in English we translate it as at home.

In this sentence, بالبيت most naturally means at home.

You may also hear في البيت, which also means in the house / at home. Both are common, but بالبيت sounds very natural here.

Yes. بالليل is a very common colloquial way to say at night or in the nighttime.

It is made of:

• بـ = in / at
• الليل = the night

So literally: in the night.

This is much more natural in Levantine conversation than a formal expression like ليلًا.

Also, the pronunciation is important:

• بالليل is pronounced bil-lēl

because the ال in الليل merges with the ل sound. That is why you hear a doubled l sound.

Yes, Arabic word order is flexible here.

بالبيت بالليل is natural and understandable: first the place, then the time.

You could also hear:

• بالليل بالبيت

Both work, but the emphasis can shift a little depending on what the speaker wants to highlight.

So the original sentence is perfectly natural, and you should not worry too much about this kind of word order at first.
