You do realize that language evolves and changes, what sounds odd to us may not in 20 years and what sounds normal now may have sounded odd 20 years ago.
Yes there are some rules, but also those rules are subject to change too.
Saying stuff like this 40 years ago would sound absurd: Google it, search it up, tweet it, download it, upload it, post it.
Language changes, thou cannest changeth with it or thee will eventually and indubitably sound like a right silly nincompoop, knave!
