I don’t think anyone invented language. I pretty sure that it naturally evolved. No one had an “ah-ha” moment about putting the noun before the predicate. “Mr. Norton walks.” So why do we torture children with diagramming sentences and picking out verbs, nouns, and adjectives? Someone at sometime (probably a word-nerd, someone fascinated with semantics or linguistics) heard all these words and sentences we naturally use, noticed a pattern of some kind, that most people used them in certain way, and decided to write down all these “rules”. Anyone that hears people speak regularly can pick this kind of stuff up naturally without ever knowing what a interjection is. But now we feel we need to sit young children down and explain these rules whether they are interested or not, as if they wouldn’t know how to speak or write if they didn’t know them in an academic form.
If you are fascinated by the rules of language, by all means study them! But you really don’t need to harass people of any age about it. If your children hear people speak in the dialect and form you desire, they will learn that language naturally. You can hear language in multiple ways. You can listen to conversation, watch TV or movies, play online role playing games, or read books. Just like learning to walk, your children learned to talk. They don’t speak like Native Americans in a old Western movie, do they? So why would they write that way?
