The term CLOG (UP) can be broken down into three words: CONGEST (7 letters), STOP (4 letters), and GUM (3 letters). Clogs are a type of footwear that originated in the Netherlands, and are now popular worldwide. They are typically made of leather or fabric and have a wooden sole. Clogs can become clogged when dirt, debris, or GUM gets stuck in the sole, preventing the wearer from walking properly. Congestion is the accumulation of something, such as dirt, debris, or GUM, which can cause clogs to form. To STOP the clog from forming, it is important to remove the obstruction. GUM is a sticky substance that can easily get stuck in the sole of a clog, causing it to become clogged.
