Guernsey is the second largest island in the Channel Islands, located 27 miles (43 km) west of the Cotentin Peninsula, Normandy. It is the largest island in the Bailiwick of Guernsey, which includes five other inhabited islands and many small islets and rocks. The Bailiwick has a population of 63,950, the vast majority of whom live on Guernsey, and the island has a land area of 24 square miles (62 km2).

Guernésiais, also known as Dgèrnésiais, Guernsey French, and Guernsey Norman French, is the variety of the Norman language spoken in Guernsey. It is sometimes known on the island simply as "patois". As one of the langues d'oïl, it has its roots in Latin, but has had strong influence from both Old Norse and English at different points in its history.
