Summary Myth 1

The meanings of words should not be allowed to vary or change

 All languages change all the time. The only language which do not change are those like Latin. Pronunciations changes as well in time, and the grammar changes also. Some people try to resist that the meaning of words change, but they actually cannot prevent it. If more people use that meaning for a word, or in that way the grammar slowly it changes and gets accepted. Languages are self-regulating systems which can be left and take care of themselves. They are self-regulating, because their speakers want to understand each other and be understood.
