Bogle A bogle, boggle, or bogill is a Northumbrian and Scots term for a ghost or folkloric being, used for a variety of related folkloric creatures including Shellycoats, Barghests, Brags, the Hedley Kow and even giants such as those associated with Cobb's Causey (also known as "ettins", "yetuns" or "yotuns" in Northumberland and "Etenes", "Yttins" or "Ytenes" in the South and South West). They are reputed to live for the simple purpose of perplexing mankind, rather than seriously harming or serving them.
