Questions & Answers about قرأت تقييما عن حاسوب مشقوقة شاشته.
Why is شاشته in the nominative case here?
In this sentence, the passive participle مشقوقة (cracked) acts like a passive verb. Because passive verbs take a proxy subject (na'ib fa'il) instead of a regular subject, the noun it acts upon, شاشة (screen), takes the nominative case with a damma: شاشَتُهُ.
حاسوب is masculine, so why is the word modifying it, مشقوقة, feminine?
This is a "false adjective" (na't sababi) structure. Instead of describing the computer itself, مشقوقة describes a part of it: the screen (شاشة). In this structure, the adjective agrees in gender with the noun that follows it (the feminine شاشة), but it matches the preceding noun (حاسوب) in case (genitive) and definiteness (indefinite).
Why is there a pronoun ـه attached to شاشته?
In a false adjective structure, the noun following the adjective must have a pronoun suffix that points back to the original noun being discussed. The masculine singular ـه links the screen back to the masculine singular حاسوب, making it grammatically clear that it is the computer's screen.
What are the exact case endings for the phrase حاسوب مشقوقة شاشته?
The phrase is read as حاسوبٍ مشقوقةٍ شاشَتُهُ. The word حاسوبٍ is genitive (majrur) due to the preposition عن. The adjective مشقوقةٍ copies that genitive case. Finally, شاشَتُهُ is nominative (marfu') because it is the proxy subject governed by the passive participle.
