Learn Turkish: Şirket anlaşmayı feshettiği takdirde tazminat öder. - In the event that the company terminates the agreement, it pays compensation.

This uses the formal conditional structure: Verb + -dIk + possessive + takdirde. The word takdirde literally means 'in the judgment' or 'at the discretion', but grammatically functions as 'in the event/case'. It requires the preceding verb to take the object participle -dIk. Since the subject terminating the agreement is Şirket (third-person singular), we add the third-person possessive -i to the participle.

What is the root of feshettiği and how do we get those consonant changes?

The root verb is feshetmek (to terminate), which is a compound of the Arabic loanword fesih and the helper verb etmek (notice the 'i' drops out). When we add the -dIk participle, the 'd' changes to 't' to match the voiceless 't' of et-, creating feshettik-. Finally, adding the possessive -i softens the 'k' to 'ğ', resulting in feshettiği.

Why does anlaşmayı take the accusative case while tazminat is left bare?

Both words act as direct objects here, but they differ in definiteness. anlaşmayı refers to a specific, previously established contract ('the agreement'), so it requires the accusative case suffix -(y)ı. tazminat refers to compensation in a general, indefinite sense ('some compensation'), so it remains in its bare form.
