Bosh bash bish
In a piece for the BBC, The Elements of Eloquence author Mark Forsyth examines a rare exception to the adjectival hierarchy: the Big Bad Wolf. Bad is opinion, and should therefore come first. However, as Forsyth points out, this phrase is too busy obeying another rule I’d never heard of: the rule of ablaut reduplication.
Other examples of the rule in action include chit-chat, singsong, flipflop and hip-hop. When you shift vowel sounds for effect this way, the vowels always follow a specific order: I, then A, then O. You’d think it was more complicated, that it depended on mood or context, but no, it’s that simple – bosh bash bish.
I don't speak my own backward pig-dog language.
