Learn Turkish: Olumsuz hava koşullarından ötürü patron toplantıyı iptal etti. - The boss canceled the meeting due to adverse weather conditions.

It pairs with the postposition ötürü (due to). In Turkish, ötürü and its synonym dolayı always require the preceding noun or pronoun to take the ablative suffix (-dan or -den).

Can you break down the suffixes in koşullarından?

Yes! The root is koşul (condition). We add the plural -lar to get koşullar. Because it is part of the noun compound hava koşulları (weather conditions), it needs the possessive suffix -ı. Then we add the buffer letter -n- (used before case suffixes on possessives), and finally the ablative suffix -dan required by ötürü.

Is there a difference between using ötürü and dolayı here?

Grammatically and in meaning, they are completely interchangeable. Dolayı is a bit more common in daily conversation, while ötürü can sound slightly more formal. In a business context like canceling a meeting, ötürü fits perfectly.

Why does toplantı take the suffix -yı?

Toplantı (meeting) is the direct object of the verb iptal etti (canceled). Because the boss canceled a specific, known meeting, it must take the definite accusative case suffix. The -y- is a buffer letter between the two vowels.
