I have been listening, for the second time, to a series of lectures by Professor Seth Lerer of the University of California at San Diego: History of the English Language, 2nd Edition, produced by The Teaching Company and included in their Great Courses series of college courses.
The lecture on Indo-European and its relationship to surviving languages, such as many of the languages spoken in the West today, is fascinating. I took notes while listening to the lecture and have attached my notes here as a downloadable Word document (above). If you are interested in languages, as I am, I think you will find the lecture fascinating.
