Learn Turkish: Yeni bir deyim öğrendiğimiz kurs çok uzaktı. - The course where we learned a new idiom was very far.

Turkish doesn't use a relative word like where in this structure. Instead, it uses the object participle -dik to describe the place. Öğrendiğimiz literally acts like an adjective meaning that we learned. When it modifies a location noun like kurs, it translates naturally to the course where we learned. Notice there is no locative suffix (like -ta) attached to kurs!

Can you break down the suffixes in öğrendiğimiz?

Sure! It comes from the verb öğrenmek (to learn). We drop the -mek and add the participle suffix -dik, followed by the possessive ending -imiz (our) to show who is doing the learning. When -imiz is added, the k in -dik softens to ğ. So, öğren + -dik + -imiz = öğrendiğimiz.

What is the subject of this sentence?

The subject is the entire phrase Yeni bir deyim öğrendiğimiz kurs (The course where we learned a new idiom). All of those words group together to describe which course we are talking about. The rest of the sentence, çok uzaktı, just tells us that it was very far.

Why does uzak have a -tı suffix in uzaktı?
