A ridge of clay or stones, particularly in agriculture or geology, or in some contexts, a type of lock or fastening.
From Old Norse kjöll, related to keel (the bottom of a ship). The maritime sense influenced the geological sense, as both refer to ridges or elevated structures.
Kell is one of those regional words that's almost extinct—most people have never heard it, but in certain farming communities, understanding kells and ridges was crucial agricultural knowledge passed down through generations before industrialization erased it.
