A ditch is usually defined as a small to moderate depression created to channel water. In Anglo-Saxon, the word dïc already existed and was pronounced 'deek' in northern England and 'deetch' in the south. The origins of the word lie in digging a trench and forming the upcast soil into a bank alongside it.
