Words are poor form of Communication. One word holds many different connotations to many different people. There's no way differentiate the words without first establishing what the word means to the speaker and the listener. That alone takes effort and time more than the words may justify. So what's the work around? Limit words? Possibly. Use precise language? Likely, but you'll run into a similar issue as I mentioned above. What does not require effort are Feelings. The Feeling of listening to music, the Feeling of Excitement, Sadness, Joy. Those Feelings are inexplainable - you just know.
So how do we Communicate through our Feelings? If I am feeling pure Joy I don't want my Joy to be diluted to mean anything other than that Feeling. And if I do then I chip away at the Essence of an emotion to relate to a blanketed term. That's backwards.
So that begs the question: "How Does One Communicate Efficiently, with the knowledge that words are a poor form?"
