The language rules we were never taught, but we somehow know them anyway, by Mark Forsyth.
“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. It’s an odd thing that every English speaker uses that list, but almost none of us could write it out.”Go ahead, try to write the sentence in a different sequence. It will sound wrong. You cannot have an old little French lovely silver whittling rectangular green knife.Why this is TOF does not know. But we will say "a steel cutting die" (material-purpose Noun) and not "a cutting steel die" (purpose-material Noun).
There are also sound patterns.
"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. If somebody said ‘zag-zig’ or ‘cross-criss’ you would know they were breaking a rule
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."
If there are three words then the vowel 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.
