How is a peak different from a fell?

A peak is generally defined as the highest point of a mountain or hill, often characterized by its prominence and distinct elevation compared to the surrounding terrain. In contrast, a fell is a term commonly used in British English, particularly in northern England, to describe a high and often barren area of land or a hill. While all fells can be considered peaks, not all peaks qualify as fells, as peaks can exist in various terrains and are not limited to the characteristics of fells.
