I live in Leeds now, but grew up in Nottingham (70 miles south, also coal-mining country) and we said "owt" and "nowt" - but pronounced like "oat", not "out".

I live in Leeds now, but grew up in Nottingham (70 miles south, also coal-mining country) and we said "owt" and "nowt" - but pronounced like "oat", not "out". Also your stereotypical Yorkshire would shorten "the" to "t'" (going down t'pit) - we would drop it completely "guin' dahn pit". Sometimes I reckon Yorkshire folks think I'm taking the piss the way I say things.
