Always been fascinated by dialects. Born in Manchester and my Grandfather used to give talks in and on Lancashire Dialect. Other grandfather was from Yorkshire which made for a good mix.
There is a four letter word beginning with a C in the thread which seems universally to be a swear word and not to be used. In the navy it was a type of rope splice.
Junior school teacher (in Cheshire) who was born and bred in the village used 'daps' to mean 'pumps' or 'plimsols' - the last of these was more common in the navy but was it related to the bloke who drew the line? That siad, I always called them 'pumps'
The movement of people has had an odd effect as I used to go through the 'ginnel' to get to a friends house but if he was walking to mine he'd go through the 'alley'. Twittens and twittings seem to be similar down South?
Things like barm cakes are also interesting. Great great uncle made 'barm cakes' in his bakery (in Oldham) and he called yeast 'barm'......hence cakes made with yeast and therefore 'bread cakes' being a bread roll. In Yorkshire they are often still called bread cakes (and I wonder if they splash them with Hendo's in Sheffield). One of my grans called them 'morning rolls' as she was a bit posh
The mention of mizzle way down near the equator ...it was used in Lancashire to mean the same thing.
Another set of interesting ones is baggin - the snack we used to have with us out in the fields. In the midlands and North East I've heard people call that snapping, and snap. Lot's more variants as you wander the country!
We used a pikle...most people say pitchfork? I have heard it called a 'two prong' by a farmer near Macc and that just sounded odd.
'Our Peg or 'our Maud' both used around the North of England for other half. I wonder if Peg is more common towards the West?
The use of 'bobbins' to mean rubbish in Cheshire is new to me. Almost always been used to mean good ...a bit like 'bob on' (presumably originally from a plumbline being perfectly straight?) by everyone I know. Can't recall anyone using it to mean bad
