Reddit reviews Txtng: The Gr8 Db8

OK I will just make points to prevent wall of texting.

Grammar =/= rules of language. It is one part of the whole thing. Grammar is also descriptive, and the rules are derives based on empirical study of the usage of native speakers. It can change, and does, naturally over time.

Beowulf was written in old english. It is a substrate precursor of middle and modern English, while an older form of french is a largely lexical contributor. I could have talked about Shakespeare, but I wanted to make more of a point. That language changes over time, even without outside pressures.

English is an evolving language that is completely unrelated to swahili, what you saying is equivalent to the crocoduck argument (http://wiki.ironchariots.org/index.php?title=Crocoduck).

Your definition of a language is pretty colloquial and quite different to the definition given by linguists, who are essentially language scientists.

I have read many books on language, sounds like you have read a school textbook on "grammar", maybe take a class in linguistics or read a book on it or something. Most of the "rules" you learn in school are heuristics and are in most cases incorrect descriptions of English syntax.

I would recommend you read this book.
