North v south inventory

I have just finished level 3 of the south course. Whilst doing it I became aware of the number of times that we were told " a very southern way of saying that is…".

I would like to explore the geographical differences, and rather than trawling through the northern version, I wondered if there was already a list created by now of the many differences?

Is there anybody out there been brave and dedicated enough to have done this already?

Thanking you in anticipation.
