A 20-hour course introducing the principles and methods of reconstruction of syntax, followed by a 20-hour workshop designed to guide students through the process of proposing analyses of grammatical change in the languages (or language families) in which they specialize. This course was especially gratifying because all the students are speakers (most natively) of the languages they are studying.
