Dear lecturers, thank you for interesting talks! My question concerns vowel harmony. In some forms of Turkish vowels in stems change, which causes violations of vowel harmony. Is it possible that after a stem vowel change can trigger changes in affixes, so that the rules of harmony are followed?

My question is about negative sentences and questions. Could you please tell more about their structure? How does the focus change in these kinds of sentences?

Dear professor Sumbatova, Thank you for interesting video lectures. My questions are related to postpositions. 1. You mentioned locative adverbs that function as postpositions. Are there postpositions themselves as a class? 2. Talking about locative adverbs, are there any language changes happening in this category? Are they getting more postposition-like? Are there any cases in which native Dargwa speakers omit inflections?
