At Yome, we have Word maps : a dialect atlas of England (http://www.librarything.com/work/1626393/book/10618777) which I recommend to anyone interested in dialects. It's rather out of date, which adds to its interest, I think, as we can see how things are moving.... I had your reaction to finding out that

My contribution to the meme (I numbered it 0) is 'What do you call the space between two buildings containing a footpath'. At Yome, the traditional answer is 'A snickelway', and from childhood in Northamptonshire, it's a jetty.

Another one: what do you say in a shop when you are handed your change?
