Although there are many calls in square dancing, some key ones include promenade, do sa do, circle left, circle right, forward and back, and swing.
Many of these basic calls are fairly intuitive and easy to figure out for a beginner on the dance floor. For example, circle right means the whole square walks to the right until they are back where they started. However, other calls are a bit more complicated, such as do sa do, where the partners turn toward each other, pass each other on the right, and circle back to where they started. A good way to learn is to watch others on the dance floor and adjust accordingly.
