الطالب قاللي انو الاستاذ مو موجود اليوم، فطلعنا من القاعة بكير.

Because لي is a attached pronoun here.
قاللي = قال + لي = he said to me.

In Levantine, these little pronouns often stick directly to the verb in writing, especially in casual text. You may also see spellings like:

• قال لي
• قالي
• قالّي

They all represent the same basic idea in dialect writing.

انو is the Levantine word that introduces a reported statement, like that in English:

• قاللي انو... = He told me that...

It corresponds roughly to MSA أنّ / إنّ, but in Levantine speech it is commonly إنو or انو. Informal spelling varies a lot, so both are normal to see.

In informal Levantine writing, the hamza is often omitted. So:

• الأستاذ is the more formal/standard spelling
• الاستاذ is a very common casual spelling

The meaning does not change. This happens a lot in dialect writing because people usually write closer to how they speak, and spelling is less fixed than in Modern Standard Arabic.

In Levantine, مو is a very common way to say not before nouns, adjectives, and participles.

So:

• مو موجود = not present / not there

You may also hear مش موجود in many Levantine varieties. Both are common, but which one sounds most natural can depend on region and speaker.

Grammatically, موجود is not a normal finite verb here. It is an active participle, but in everyday Arabic it often functions like an adjective meaning:

• present
• there
• available
• existing

So الاستاذ مو موجود اليوم literally feels more like:

• The teacher is not present today
• The teacher is not there today

Because in Arabic, the present-tense to be is usually omitted.

English needs:

• The teacher is not present today

Levantine just says:

• الاستاذ مو موجود اليوم

This is completely normal. Arabic usually does not say a separate word for is/am/are in present-tense sentences like this.

اليوم is a time expression, and in Levantine it often comes after the main description:

• الاستاذ مو موجود اليوم

That word order is very natural. Arabic is fairly flexible, so other orders are possible too, but this one sounds straightforward and common.

The فـ means something like:

• so
• then
• as a result

So:

• فطلعنا = so we left / then we went out

It connects the second action to the first one as a consequence. The idea is: the student told me the teacher was not there, so we left early.

طلعنا is the past tense of طلع with the we ending -نا.

So:

• طلع = he went out / came out / went up
• طلعنا = we went out / we left

In this sentence, the natural meaning is we left or we went out.
This verb is very common in Levantine and can have several related meanings depending on context, such as go up, come out, leave, or turn out.

The ending -نا marks the subject we in the past tense.

So:

• طلعت = I went out / left
• طلع = he went out / left
• طلعنا = we went out / left

This is different from attached object pronouns like the -لي in قاللي.
In طلعنا, -نا is part of the verb conjugation and shows who did the action.

من means from, so:

• من القاعة = from the hall / classroom / lecture room

It tells you where they left from. With طلع or طلع من, Arabic often uses من to show the place someone exited.

بكير means early.

Putting it at the end is very natural in Levantine:

• طلعنا من القاعة بكير

This is similar to saying We left the room early in English.
Adverbs like بكير often come near the end of the clause, though word order can be somewhat flexible.

In الطالب, the ل of الـ is not pronounced normally because ط is a sun letter.

So الطالب is pronounced roughly like:

• eṭ-ṭāleb

not like:

• el-ṭāleb

By contrast, in الأستاذ / الاستاذ, the ل is pronounced because the next sound is not a sun letter.

Both noun-first and verb-first patterns exist in Arabic, but in Levantine, starting with the noun is very common in everyday speech:

• الطالب قاللي...

This structure feels natural for introducing the topic first: the student.
You can also hear verb-first orders in Arabic, but this noun-first order is especially common in spoken Levantine conversation.

Yes. Depending on context, مو موجود can mean:

• not here
• not there
• not available
• absent
• not present

That is why موجود is such a useful everyday word. Its exact English translation depends on the situation. In this sentence, it most naturally means the teacher was absent or not there today.
