Who's The Decider

When it comes to language, a listener from Dallas wants to know, as a fellow Texan might put it, "who's the decider"? Grant explains that nobody makes the rules about language, and everybody does. For those seeking professional guidance, a whole community of lexicographers, dictionaries, and style guides offers rules and provenance on vocabulary, grammar, and pronunciation. However, on a daily basis all the users of a language implicitly write the rules by choosing words and syntax that have semantic clarity for the people they're trying to communicate with. You could go to a reference book, or you could say something to your neighbor, then judge by their reaction whether or not you made sense. This is part of a complete episode.
