The human mind understands and interprets reality through the use of words and language. A one to one correlation between every sign, object, event or place in reality and a linguistic word for it would make language unwieldy and overly burdensome, as well as, nearly impossible to learn. It is the use of repetitious words in different arrangements that we communicate reality. With this understanding, just as a picture conveys a thousand words, so does a pun or metaphor convey board meanings with few words. And so the pun or metaphor to be understood one must know the context in which is was used.
