Questions & Answers about استوفيت المتطلب بنفسي.
Why does the verb استوفيت end with a ي instead of an alif maqsurah (ى)?
The base verb is استوفى, a Form X verb from the root و-ف-ي. Because it is a defective verb (ending in a weak letter), the final alif maqsurah (ى) changes back to its original root letter, ي, when you attach a pronoun suffix like the first-person ـتُ. This is why استوفى becomes استوفيتُ.
What is the grammar behind the noun المتطلب?
It is the Form V passive participle of the root ط-ل-ب (to request/seek). The Form V passive participle pattern is مُتَفَعَّل. Used as a noun, مُتَطَلَّب literally translates to "that which is demanded" or "required," hence "requirement" or "prerequisite."
Could I drop the بـ prefix and just say نفسي to mean "myself"?
Dropping the بـ changes the nuance slightly. بنفسي means "by myself" or "on my own" (indicating you did the work alone). If you just used نفسي, it would act as an emphatic apposition meaning "I, myself, fulfilled it," but بنفسي is much more common and natural for expressing "I did it personally or independently."
What are the unwritten case endings (i'rab) on the noun المتطلب?
It takes a fatha (ـَ) on the final letter (ب), making it المتطلبَ (al-mutaṭallaba). This is because it is the direct object of the verb (in the accusative/mansub case).
