The term 'move round and round' can be described by several words, such as EDDY (4 letters), ROTATE (6 letters), CIRCLE (6 letters), GYRATE (6 letters), CIRCULATE (9 letters), and TWIRL (5 letters). An EDDY is a small circular movement of air or water, often caused by an obstruction in the flow. ROTATE means to turn around a central point. CIRCLE is a closed curved line that goes around a fixed point. GYRATE is to move in a spiral or circular path. CIRCULATE is to move around in a continuous stream. TWIRL is to spin around quickly. All of these words describe the same action of moving round and round.
