The term RUB RAW is composed of two words, CHAFE (5 letters) and ABRADE (6 letters). CHAFE means to wear away by friction, while ABRADE means to scrape or wear away by rubbing. Both words describe the action of rubbing something in a way that causes it to become worn down or damaged. This type of rubbing can be used to remove dirt or grime from a surface, or to create a desired texture or shape. In some cases, it can also be used to create a desired color or finish.
