A fascinating read, Miia, thanks for the link. I do have a question, though. Since you excluded non-American variants of English (for very sensible reasons, well outlined in your original thread), would it not have been advisable to define the word "English" at the beginning of the thesis? Since the thesis confines itself to one variant of English, ought not that have been noted at the outset?
