The term PART OF A BOW can be solved by two four-letter words: KNOT and LOOP. A KNOT is a type of fastening made by tying a rope or string into a series of loops and twists. It is often used to secure items together, such as tying a boat to a dock. A LOOP is a curved or circular shape that is formed when a line or rope is bent around and crosses itself. It is commonly used in archery, where it is part of the bow and helps to create tension when the bowstring is pulled back.
