Internally Headed Relative Clauses in Japanese and Navajo

PDF says on internally headed relative clauses in Japanese and Navajo. It has some pretty good, um, you know, glosses and it goes through Japanese samples. Internally headed, for example, John picked an apple or John picked up an apple, which was on a plate. So that's something. I actually didn't know about this first one, the internally headed of relative pause in Japanese.
