I hope I am not a pedant, but even those who are must enjoy this artful commentary:
Language should be enjoyable. There are circumstances that call for correctness and others that call for pleasure. Being grammatically wrong can be fun if it is intentional. So what’s “wrong”? There are basic grammatical rules for communication that should be adhered to in order to be understood and that keep one from being thought of as illiterate or unintelligent. Then there are more specific rules that keep writing or speaking from being unclear or unpleasant as a result of confusion. These are the “rights” and “wrongs” of grammar.
It is important to know the difference between grammar and style, but that’s another post. Stay tuned, and meanwhile, enjoy your language.
