Questions & Answers about تصفية الخيارات مهمة قبل الحجز.
Why is the adjective مهمة feminine? Is it agreeing with the plural word الخيارات?
No, it is agreeing with تصفية (filtering), which is the main subject of the sentence and a feminine noun. The phrase تصفية الخيارات forms an Idafa (possession structure) meaning the filtering of the options. As the predicate of the sentence, the adjective must agree with the head noun of the subject, which is the first word.
What is the root of تصفية and what are its other common meanings?
The root is ص-ف-ي, which relates to being pure or clear. As a Form II verbal noun, تصفية literally means the act of purifying or clearing. Besides filtering, you will frequently see it at this level meaning liquidation (of a business) or elimination (in a sports tournament or of a target).
Why doesn't the word تصفية have the definite article ال attached to it if we are talking about a specific filtering?
Because تصفية is the first word in an Idafa construction. The rules of Arabic grammar state that the first word of an Idafa never takes the definite article ال, but the phrase as a whole is still grammatically definite because the second word (الخيارات) is definite.
How does قبل affect the grammar of the word الحجز?
Words indicating time or location like قبل (before) and بعد (after) act as the first part of an Idafa structure. Therefore, the noun that directly follows them, like الحجز (booking), acts as the second part of the Idafa and must take the genitive case (majrur).
