Communication between human beings is accomplished through various means and methods.  No one way is perfect, and often some kind of teamwork of method is required.  But we can agree that the most often used method is the word.  Written or spoken, words carry the bulk of that effort.  We do realize that communication through words, even when enhanced by gestures, punctuation, emphasis and context is not perfect.  Somehow, the process of trying to take an image or thought or impression or feeling from inside of one person to the mind or heart (or both) of another is only successful to a degree.  Definitions of words both between languages as well as within languages, due to experience and time are not always the same.  One obvious example of that right now is the language used by our grand children which seems almost foreign to us old people.  It is as though they have been brought up in a different world.  (Which may be true in a way!)  A word, whether spoken, written, put to music or poetry, on a billboard, an i-pad or used in any of several different kinds of media doesn't always represent the same thing to the hearer, the reader, the listener or the observer.  Considering the challenges to 'perfect' communication, it is a wonder that we do as well as we do, but it is also important to be aware of the challenge of communicating effectively.
