It is very useful, when one is young, to learn the difference between "literally" and "figuratively." If something happens literally, it actually happens; if something happens figuratively, it feels like it is happening. If you are literally jumping for joy, for instance, it means you are leaping in the air because you are very happy. If you are figuratively jumping for joy, it means you are so happy that you could jump for joy, but are saving your energy for other matters.
