Definition: Yorkshire is a region in north-western England, especially in the county of Yorkshire (Wales). It has been known to be one of the oldest regions in Europe. The name "Yorkshire" comes from Old English "Wyrdyn", which means "the place where the waters are low". The area around York and other major cities like Lincoln and Sheffield is also known as Yorkshire because it's often associated with its importance in Anglo-Saxon history, particularly during the 8th century.
