Hi there. I have never studied Turkish, so I came here to see if someone can clarify something for me. I would like to know where are the boundaries in vowel harmony rules. More precisely, I'd like to know if separable postpositions (I've read there are some and I don't know if there are any prepositions), conjunctions and any kind of unnaccented word follow this rule. And if they do, do they have internal harmony or do they follow the harmony from the previous/following word? And if you can point me to some paper discussing the matter I would be very grateful. Thanks, L.
