Questions & Answers about أصبحت الإثارة كبيرة للذين جربوا الغطس.
Why does the adjective كبيرة take the accusative case here?
Because of the verb أصبحت (became). Like كان (was), it is one of the 'sisters of Kana'. It leaves its subject الإثارة (the thrill) in the nominative case but changes its predicate كبيرة (great) to the accusative case, so it is read as كبيرةً (kabiiratan).
What happens to the spelling when adding the preposition لـ (for) to الذين (those who)?
When the preposition لـ attaches to a word starting with ال, the initial alif drops out entirely. So لـ + الذين merges into للذين (for those who).
How would we change this sentence to use the 'one of the greatest' pattern from this lesson?
To use the lesson's pattern, you would combine من (one of), the superlative adjective أكبر (greatest), and the definite plural noun for thrill. The phrase would become من أكبر الإثارات (one of the greatest thrills) instead of just using the base adjective كبيرة (great).
Why is there an extra alif at the end of the verb جربوا?
The silent alif at the end of جربوا (they tried) is a standard spelling rule for past and present plural verbs. It is added after the plural waw suffix to show that the waw is a plural marker, preventing confusion with roots that naturally end in the letter waw.
