I began this project back in 2005 as a side interest to my main research into the cultural history of the Irish language. Since that time, I've made halting progress on a few central problems that need to be solved in order to get to my goal: a clearer understanding of the timing and demographic features of Ireland’s nineteenth-century language shift. Last summer, after a few months of soaring success as I applied what appeared to be clear solutions to these problems, work came to a screeching halt when the numbers I was producing stopped making sense (more on this in coming posts).
