اذا انتي تعبانة، لا تدرسي كتير بالليل.

Yes. انتي is you addressed to one female in Levantine Arabic.

A native English speaker often notices that Arabic distinguishes:

• إنتَ / إنت = you masculine singular
• إنتِ / إنتي = you feminine singular

So this sentence is being said to a woman or girl. In more formal Standard Arabic, you would usually see أنتِ.

Because the adjective has to agree with the person being described.

Here:

• انتي = you feminine singular
• تعبانة = tired feminine singular

If you were talking to a man, it would be:

• إنت تعبان

This kind of adjective agreement is very important in Arabic.

In Arabic, the verb to be is usually omitted in the present tense.

So:

• انتي تعبانة literally looks like you tired
• but it means you are tired

This is completely normal. Arabic does this all the time in the present tense.

If you wanted past tense, then a form of كان might appear, for example:

• كنتِ تعبانة = you were tired

اذا is commonly used for a real or likely condition: a normal if meaning in case this situation happens.

So here it means something like:

• if you are tired...

Learners often compare it with لو:

• اذا = neutral, real possibility
• لو = often more hypothetical, unreal, or softer depending on context

In this sentence, the speaker is talking about a realistic situation, so اذا fits well.

Because this is a negative command: don’t study.

In Arabic:

• ادرسي = study! said to one female
• لا تدرسي = don’t study! said to one female

So after لا, Arabic uses a present-tense form to make the negative command.

Also, the ending -ي in تدرسي shows that the command is addressed to a feminine singular person.

It is understandable, and many speakers will say it, but it sounds a bit closer to Standard Arabic or a more careful style.

In very everyday Levantine, many people would also say:

• ما تدرسي كتير بالليل

So a learner should know:

• لا تدرسي = correct and clear
• ما تدرسي = very common in spoken Levantine

The sentence you were given mixes clearly Levantine words like انتي and كتير with a somewhat more standard-style negative command.

Here كتير means a lot or too much, because it is modifying the verb تدرسي.

So:

• تدرسي كتير = study a lot

A useful thing to know is that كتير can also mean very with adjectives:

• كتير منيح = very good
• كتير تعبانة = very tired

So its exact English translation depends on what it is modifying.

بالليل means at night or during the night.

It is made of:

• بـ = a preposition often meaning in / at
• الليل = the night

Together:

• بالليل = at night

This is a very common time expression in Levantine.

Sometimes Arabic can drop subject pronouns, but here keeping انتي is very natural because the sentence starts with a condition and then gives a description.

So:

• اذا انتي تعبانة... sounds clear and natural

If you remove it, اذا تعبانة... may be understood in context, but it sounds less complete on its own.

So for learners, keeping انتي here is the safest and most natural choice.

You would change the feminine forms to masculine:

• اذا انت تعبان، لا تدرس كتير بالليل.

The changes are:

• انتي → انت
• تعبانة → تعبان
• تدرسي → تدرس

This is a good example of how Arabic changes pronouns, adjectives, and verb forms depending on gender.
