I am working on relative clauses in Kyrgyz. Kyrgyz and some other Turkic languages show agreement of subject with object in relative clauses, instead of the verb. It is an SVO language.
Menin okugan kitabim I-Gen read-rel.suf. book-1st persn "The book that I read"
Are there other languages that show an agreement of subject with object, but not with verb in relative clauses? What can be the cause of it?
