Questions & Answers about Yarınki sınav zor olacak.

What is the function of the suffix -ki in yarınki?

-ki is a derivational suffix that turns a noun or time expression into an adjective meaning “of that X.” Here yarın (tomorrow) + -ki = yarınki, so yarınki sınav literally means “the exam of tomorrow,” i.e. “tomorrow’s exam.”

Why is yarınki written as one word without an apostrophe?

In Turkish, suffixes attach directly to common nouns without an apostrophe or hyphen. Apostrophes are only used when adding suffixes to proper names (e.g. Türkiye’de). Since yarın is not a proper noun, its suffix -ki is simply appended: yarınki.

Does -ki change form according to vowel harmony (like -lar/-ler)?

No. The adjectival -ki is invariant—it always appears as -ki, regardless of the vowels or consonants in the base word. It does not follow Turkish vowel harmony.

Could I say yarının sınavı zor olacak instead? What’s the difference?

Yes, yarının sınavı zor olacak uses the genitive (yarının) + possessive (sınavı) construction and also means “tomorrow’s exam will be difficult.”
Difference:
• yarınki sınav is a straightforward adjective form and more idiomatic for time expressions.
• yarının sınavı is grammatically correct but a bit heavier (two case/possessive endings). Both are understood the same.

Why is there no article like a or the before sınav?

Turkish does not have indefinite (a/an) or definite (the) articles. A bare noun can be definite or indefinite from context. Here, yarınki sınav clearly refers to a specific exam (“the exam that is tomorrow”), so no article is needed.

Why do we need olacak? Can we just say sınav zor?

Turkish predicates need a verb. To express future tense with an adjective, you use olmak (to be) in its future form.
• zor alone is an adjective and cannot stand as the main verb.
• zor olacak = “will be difficult.”
Dropping olacak would make the phrase ungrammatical.

How do I make this negative or turn it into a question?

Negative: Insert ma/mé before the tense ending:
• Yarınki sınav zor olmayacak. = “Tomorrow’s exam won’t be difficult.”
Question: Add -mı/-mi after the verb or use intonation:
• Yarınki sınav zor olacak mı? = “Will tomorrow’s exam be difficult?”

How would you say “in tomorrow’s exam” (e.g. “In tomorrow’s exam, I will need more time”)?

Keep yarınki unchanged, then add the locative case -da to sınav:
• Yarınki sınavda daha fazla zamana ihtiyacım olacak.
Here sınavda = “in the exam.”

What are some other time expressions that use -ki?

You can attach -ki to many temporal words to form adjectives:
• bugünkü (“today’s”) – bugünkü haberler
• dünkü (“yesterday’s”) – dünkü toplantı
• geçen haftaki (“last week’s”) – geçen haftaki proje
• gelecek seneki (“next year’s”) – gelecek seneki tatil

Where does the stress fall in Yarınki sınav zor olacak?

Turkish words are typically stressed on the last syllable:
• Yarınkí (ya-rın-Kİ)
• sınáv (sı-NAV)
• zór (ZOR)
• olacák (o-la-CAK)
In a full sentence, the main intonational stress often lands on the last word (olacak).
