المدير هيمضي على الاستمارة بعد الاجتماع.

It is Egyptian Arabic.

The clearest clue is هيمضي. In Egyptian, هـ / حـ is a common future marker, so هيمضي means he will sign. In MSA, you would normally expect سـ or سوف, such as سيمضي or more commonly سيوقّع.

Another clue is that there are no case endings, which is normal in spoken Egyptian.

هيمضي is basically:

• هـ = future marker
• يمضي = he signs / he is signing

So together, هيمضي = he will sign.

In informal Egyptian writing, you may also see the future marker written as حـ, so حيمضي can represent the same idea.

Because in this meaning, the usual expression is يمضي على = to sign a document.

So Arabic uses a verb + preposition pattern here:

• يمضي على الاستمارة
• literally something like sign on the form
• naturally: sign the form

This is very common in Arabic: a verb may require a preposition even when English does not.

Yes, يمضي على is natural, especially with official papers or forms.

But يوقّع على is also very common, and in casual speech many speakers may use it even more often:

• المدير هيمضي على الاستمارة
• المدير هيوقّع على الاستمارة

Both are good. يمضي can feel a bit more formal or official in some contexts.

Because subject-first word order is very common in Egyptian Arabic.

So:

• المدير هيمضي... = very natural in Egyptian

Starting with the subject makes the manager the topic of the sentence.

In MSA, verb-first order is more common, but in everyday Egyptian, subject-first is usually the most natural choice.

Because they are all definite:

• المدير = the manager
• الاستمارة = the form
• الاجتماع = the meeting

Arabic uses الـ as the definite article, like the in English.

In Egyptian pronunciation, الـ is usually said as el- or il-, so you will often hear:

• el-modīr
• el-estimāra
• el-egtimāʿ

بعد means after.

It is followed directly by the noun:

• بعد الاجتماع = after the meeting

You do not need an extra word like of. This is a normal Arabic structure.

Also, a time phrase like this often comes at the end of the sentence, which is exactly what happens here.

A helpful rough pronunciation is:

el-modīr hayemḍi ʿala l-estimāra baʿd el-egtimāʿ

A few useful pronunciation notes:

• ج in اجتماع is pronounced like a hard g in Egyptian
• ع in بعد and اجتماع is the consonant ʿayn
• ض in يمضي is an emphatic d sound

So the last part sounds roughly like baʿd el-egtimāʿ.

It does not have to stay at the end, but the end position is very natural.

So this sentence is perfectly normal as:

المدير هيمضي على الاستمارة بعد الاجتماع

If you move بعد الاجتماع earlier, it can add emphasis or change the flow, but the original order is the most straightforward everyday phrasing.
