اذا عندك دوام بكير بكرا، نام بكير اليوم.

Yes. In Levantine, اذا means if, just like MSA إذا.

A few useful notes:

• In casual writing, people often write اذا without the hamza.
• You may also see إزا, which reflects the spoken pronunciation more closely.
• In Levantine, it is usually pronounced something like iza.

So اذا عندك دوام... means if you have work/classes...

عندك literally means at you or by you.

Levantine Arabic often expresses possession with عند + a pronoun suffix:

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

So:

• عندك دوام = you have work / you have classes / you have a shift

This is a very common Arabic way to say have.

دوام is a very common word that refers to your regular scheduled work or study time.

Depending on context, it can mean:

• work
• a work shift
• school
• classes
• office hours / duty hours

So عندك دوام بكير بكرا could mean:

• you have work early tomorrow
• you have class early tomorrow
• you have an early shift tomorrow

It is broader than just job.

They are different words:

• بكير = early
• بكرا = tomorrow

So:

• دوام بكير = early work / an early shift / classes early
• بكرا = tomorrow

Even though they look similar, they do different jobs in the sentence.

A rough pronunciation difference is:

• بكير ≈ bkiir
• بكرا ≈ bukra or bokra, depending on the speaker

It can work like either one, depending on context.

In this sentence:

• دوام بكير = literally something like early work/classes
  Here it behaves a bit like an adjective.
• نام بكير = sleep early
  Here it behaves like an adverb.

This is very normal in Arabic. One word can often cover both ideas without needing separate forms like English sometimes does.

نام is the imperative form, so it means sleep!

In this sentence, it is a command or strong suggestion:

• نام بكير اليوم = sleep early today / go to sleep early tonight

This specific form is addressed to one male.

If you were speaking to a woman, you would usually say:

• إذا عندِك دوام بكير بكرا، نامي بكير اليوم.

If you were speaking to more than one person:

• إذا عندكم دوام بكير بكرا، ناموا بكير اليوم.

So yes, both the have part and the command can change depending on who you are talking to.

Because in everyday speech, today can naturally imply tonight when the action is sleeping.

So:

• نام بكير اليوم sounds natural and means sleep early today / tonight

A speaker could also say:

• نام بكير الليلة
• نام بكير هالليلة

Those are more explicitly tonight. But اليوم is completely normal here.

From an English point of view, it may feel like something is missing, but in Arabic it is not.

Arabic often does not use a present-tense verb meaning to be in sentences like this.

So instead of saying something like:

• if you are having work early tomorrow

Arabic simply says:

• اذا عندك دوام بكير بكرا

Literally, it is more like:

• if at-you early work tomorrow

That is a complete and natural structure in Arabic.

Yes, it is natural.

It sounds like a normal piece of advice. A speaker might also say similar versions, such as:

• إذا عندك شغل بكير بكرا، نام بكير اليوم.
• إذا بكرا عندك دوام بكير، نام بكير اليوم.

These are all natural. The original sentence is perfectly fine.

A small nuance:

• دوام is more about scheduled attendance, work hours, or classes
• شغل is more generally work

So دوام fits especially well if you mean an early start time.

A common pronunciation would be:

iza ʿindak dawām bkīr bukra, nām bkīr il-yōm

A few pronunciation notes:

• اذا → iza
• عندك → ʿindak
• بكير often sounds like bkīr
• بكرا often sounds like bukra or bokra
• اليوم → il-yōm

You would usually make a small pause after بكرا:

iza ʿindak dawām bkīr bukra, / nām bkīr il-yōm

Not really. It is better to understand the whole chunk naturally rather than word-for-word.

دوام بكير بكرا means:

• work early tomorrow
• an early shift tomorrow
• classes early tomorrow

Arabic often lets time words like بكرا attach to the whole phrase very smoothly, so the most natural English translation depends on context, not on matching each word one by one.
