Newfoundland and Labrador's capital and largest city, St. John's, is home to nearly 40 percent of the province's population. St. John's is the seat of government, home to the House of Assembly of Newfoundland and Labrador and the highest court in the jurisdiction, the Newfoundland and Labrador Court of Appeal. The name Newfoundland is derived from English as "New Found Land" (a translation from the Latin Terra Nova). The origin of Labrador is uncertain; most authorities credit it to João Fernandes Lavrador, a Portuguese explorer, and lavrador a title meaning "landholder".
