A pointed projection is a type of object that has a sharp end or tip. The term can be broken down into four parts: PRONG (5 letters), BARB (4 letters), PROW (4 letters), and CUSP (4 letters). A PRONG is a thin, pointed piece of metal or other material that is used to hold or fasten something in place. A BARB is a sharp point or hook that is used to catch or hold something. A PROW is the pointed front part of a ship or boat. Finally, a CUSP is a pointed or curved end of an object. All of these words describe a pointed projection, which is an object with a sharp end or tip.
