not to say that it’s not a valid English dialect
I was in a store the other day and ended up talking to a guy from Bradford North England (which, he said, is know for three things, two of which are Indian food and riots). Accents from Bradford, are apparently quite heavy–I could understand him but not without a bit of effort on my part.
It turns out this guy has been teaching English in Taiwan for 7.5 years. Anyone else see a problem with teaching an accent that’s not very well understood by many English speakers?
