Your first question was, ”But what is the value of the same word having two very different meanings?” The answer to how does the same word having two different meanings have any value is that it allows person to use a word that has a general accepted understanding to make a point based on the context in which the word is used. Basically, the value is the ability for two person to communicate on a specific topic in which both due to the context of the statement have a mutual understanding as to the words meaning.

My question is what gives any profession the right to capture a word, define it, and forbid others from using it in another context.
