- and 'ere's the pronunciation:

"Skawn" to rhyme with "dawn"

"Skonn" to rhyme with "upon"


As to "scunner"; in some Eng. dialects, this word means "to skin", as in to remove the skin from an animal (after you've killed it, of course !)

A metaphorical usage is, "Yon stink's enough to scunner a toad!" - i.e, the stench is powerful enough to remove a toad's skin.
I just can't remember in which part of England I heard this: I think it was North Midlands - Nottingham/ Derbyshire/ Staffordshire sort of area.
