Unseen Law

[...] adjectives in English absolutely have to be in this order: opinion-size-age-shape-colour-origin-material-purpose Noun. So you can have a lovely little old rectangular green French silver whittling knife. But if you mess with that word order in the slightest you'll sound like a maniac. Ifs an odd thing that every English speaker uses that list, but almost none of us could write it out. And as size comes before colour, green great dragons can't exist. -- Mark Forsyth’s The Elements of Eloquence

Actually, there are a couple of small exceptions. Little Red Riding Hood may be perfectly ordered, but the Big Bad Wolf seems to be breaking all the laws of linguistics. Why does Bad Big Wolf sound so very, very wrong? What happened to the rules? Well, in fact, the Big Bad Wolf is just obeying another great linguistic law that every native English speaker knows, but doesn’t know that they know. And it’s the same reason that you’ve never listened to hop-hip music. You are utterly familiar with the rule of ablaut reduplication. You’ve been using it all your life. It’s just that you’ve never heard of it. But if somebody said the words zag-zig, or ‘cross-criss you would know, deep down in your loins, that they were breaking a sacred rule of language. You just wouldn’t know which one.

Reduplication in linguistics is when you repeat a word, sometimes with an altered consonant (lovey-dovey, fuddy-duddy, nitty-gritty), and sometimes with an altered vowel: bish-bash-bosh, ding-dang-dong. If there are three words then the order has to go I, A, O. If there are two words then the first is I and the second is either A or O. Mish-mash, chit-chat, dilly-dally, shilly-shally, tip-top, hip-hop, flip-flop, tic tac, sing-song, ding dong, King Kong, ping pong. -- Mark Forsyth [link]
