Never heard this word in my life.. We say 'piws' in North Wales, at least
I have never heard porffor either. Interesting to find out how many differences there are between the north and south!
Piws more widely used?
piws is far more widely used
As a South Walian I recognise and use both porfor and piws, but mainly use porffor.
Same here. piws does seem to be more common among North Walian friends.
