Questions & Answers about الكهربائي جدد تلك الأسلاك.
How does the Form II verb work in جدد?
جدد (jaddada) is the past tense "he" conjugation of a Form II verb. Form II is built by doubling the middle letter of the root, which gives it an extra emphasis (often written with a shadda symbol). Here, it takes the root ج-د-د (related to جديد, meaning "new") and applies the Form II pattern to mean "to renew" or "he renewed".
Why is the feminine singular word تلك used for "those wires"?
In Arabic, all non-human plurals are grammatically treated as feminine singular. Since الأسلاك (wires) is a non-human plural (the singular is سلك), any demonstrative pronoun referring to it must be feminine singular. That's why we use تلك ("that") instead of a plural word for "those".
Is الكهربائي an adjective or a noun?
It functions as a noun here ("the electrician"), but it is built just like a "nisba" adjective. It comes from the word كهرباء (electricity) plus the ـيّ suffix, which means "related to". So it literally means "the electrical [person]".
Can I put the verb first and say جدد الكهربائي تلك الأسلاك?
Yes, absolutely! The current sentence is a nominal sentence because it starts with a noun (Subject-Verb-Object). Starting with the verb creates a verbal sentence (Verb-Subject-Object). Both structures are completely natural and correct in Arabic.
