Learn Turkish: Taraflar uyuşmazlığı çözmediği takdirde avukatla görüşürüz. - In the event that the parties do not resolve the dispute, we will speak with the lawyer.

It acts as a formal alternative to the standard -se conditional, translating to 'in the event that'. We take the verb çözmek (to resolve), add the negative -me, the participle -dik (which softens to -diğ-), and the 3rd-person possessive -i. The word takdirde means 'in the case', so the whole phrase literally means 'in the case of their not resolving'.

Since the subject is the plural taraflar (the parties), why is it çözmediği and not the plural çözmedikleri?

In Turkish, when a 3rd-person plural subject is explicitly stated in the sentence (like taraflar), the verb or participle often just takes the singular 3rd-person suffix. You could correctly say çözmedikleri, but çözmediği is perfectly natural and standard.

How is the word uyuşmazlığı (the dispute) formed?

It comes from the verb uyuşmak (to agree or harmonize). Adding the negative aorist suffix -maz and the noun-maker -lık creates uyuşmazlık (disagreement or dispute). Because it is the specific direct object of the verb çözmek, it takes the accusative suffix -ı, causing the final -k to soften to -ğ.

Why use görüşürüz instead of for 'we will speak'?
