The word
"roll" can have a few different meanings, but in simple terms, it often refers to the action of moving or rotating something in a particular way. For example, you can
roll a ball by making it move forward while turning in a circular motion. You can also
roll up a piece of paper by winding it into a cylinder shape. So,
"roll" generally implies the action of turning or moving something in a circular or winding motion.
