A turn is a component of a knot. Turns can be made around objects, through rings, or around the standing part of the rope itself. Turns come in various forms, distinguished by the number of passes that the rope makes.A turn or single turn requires one pass. The line makes a U-shape through or around the object, or half a revolution. A round turn requires two passes and makes one and a half revolutions. Two round turns adds another pass and revolution.
