Newfy “English” is the Quebecois of English dialects. It’s barely understandable by the rest of the country. An Englishman and an american/Canadian will be able to understand one another mostly with no problem. There will be the odd slang word that trips 'em up but, overall, the message comes across. Newfy is hard to understand what most words are, the accent is thick.

Similar to a Scottish or Welsh accent, I should think, to north Americans.

OP what does the question mean?

Your post just asks what the Quebecois is, but you forget to say what it means to ‘be a Quebecois’
