How important are dictionaries?
Language changes over time. The English we speak now isn't the same as the English we spoke 100 years ago. Language varies over regions. English is not quite the same in England, Australia, and the United States because we have different dialects. It's probably impossible to stop language from changing. I'm not even sure it would be a good think if we could stop it.
The question I'm asking myself right now is what should be done when people disagree about the meaning of a word. Should dictionaries always be the final authority on what a word means? If so which dictionary has the most authority? Can people in a discussion simple agree with each other on a specific set of definitions? What happens when people can't agree? Is there any point to having an argument over what the proper definition of certain words should be? Every argument I've seen about definition on this site seemed utterly pointless.
The world is more connected now then at any other point in history. People from all over the world can connect with each other online. I wonder what affect this connection will have on language. I wonder if dictionaries will become more important or less.
