Puns were used by Shakespeare to explain meaning, to make sense of the world around his characters. If a certain scene in his play was a bit confusing, he would often use a pun, which is a play on words, in order to explain what is happening in more detail. His puns were very clever, and many of them are still used today, without people even realizing how old they actually are.
