Guernésiais is the language of Guernsey. Pronounced 'JEHR-nehz-yay', it is also known as 'Guernsey French' or 'patois'. It is a form of Norman French, which evolved from the Vulgar Latin spoken in the region when it was part of the Roman Empire. Many different regional languages evolved in France before the modern 'standard' French was agreed. One of these languages was Norman, and was spoken in the islands a thousand years ago when we were ruled by the Dukes of Normandy.
