The Meanings of Words Should Not be Allowed to Vary or Change

All languages change all the time. Languages change their pronunciations through time. Grammatical structures also change. The most obvious way languages change in is in the usage and meaning of words. A number of people seem to think that the fact that languages change the meanings of their words in this way is unfortunate. They believe that change in language in inherently undesirable and that we should do everything we can to stop it because change can be dangerous and confusing. This leads such people to argue that it makes sense to determine what a words means by looking at its origins. 

The English language is full of words which have changed their meanings slightly or even dramatically over the centuries. Emotive words tend to change more rapidly by losing some of their force. There are not any difficulties caused by the change of the meaning of a word, because people did not know the original meaning in the first place.
