Learn Hardcore Turkish: Yarınki sınav zorlu olacak.

Yarınki comes from the noun yarın (meaning tomorrow) with the suffix -ki added to form an attributive adjective. This construction turns yarın into yarınki, which translates as tomorrow's, indicating that the exam in question is scheduled for tomorrow.

How is the future tense expressed in the sentence?

The future tense is shown with the verb olacak, which is the future form of olmak (meaning to be). In this sentence, olacak translates to will be, clearly conveying that the exam is expected to be difficult.

What role does the adjective zorlu play in the sentence, and what is its root?

Zorlu is an adjective meaning difficult or challenging. It is derived from the root zor (meaning hard). In the sentence, zorlu modifies sınav (exam), describing the exam's challenging nature.

Why is yarınki used instead of simply yarın when referring to the exam?

In Turkish, yarınki specifically turns yarın into an adjective that qualifies a noun—in this case, sınav. Using yarınki sınav means tomorrow's exam, clearly linking the exam to the day it is scheduled, whereas yarın on its own would typically function as an adverb meaning tomorrow rather than as a descriptive modifier.
