Learn Hardcore Arabic (Egyptian): المصاريف الادارية بعد الموافقة المبدئية. - The administrative fees come after the preliminary approval.

الـ is usually pronounced el- in Egyptian.
ص in مصاريف is an emphatic s sound.
ق in موافقة is usually pronounced as a glottal stop in Egyptian, so موافقة sounds like mowāf'a.
ة at the end of إدارية / مبدئية / موافقة is pronounced -a / -ya depending on the word and context.

In a more careful formal reading, you may also hear something closer to:

al-maSārīf al-idāriyya baʿda al-muwāfaqa al-mabda'iyya

Is this a full sentence?

Not really. It is more of a phrase or heading than a complete sentence.

In English, something like Administrative fees after preliminary approval can appear on a form, website, or document without needing a verb. Arabic does the same thing very often.

So this is perfectly normal as a label or document heading.

What does المصاريف mean exactly, and why is it plural?
