Delineates is a term used to describe the action of creating a clear and precise outline or boundary. It can be done in various ways, such as etching, limning, drawing, tracing, and marking out. Etching involves using a sharp tool to carve a design into a hard surface. Limning is the process of painting or drawing on a surface with a brush or pen. Drawing is the act of making a picture or diagram with a pencil, pen, or other instrument. Tracing is the act of copying a design by placing a sheet of paper over it and drawing over it. Marking out is the process of making a plan or sketch of something before it is built. All of these methods are used to delineate an outline or boundary.
