The English language is a wonderful thing, and we know some rules without knowing we know them.

‘Have you ever heard that patter-pitter of tiny feet? Or the dong-ding of a bell? Or hop-hip music? That’s because, when you repeat a word with a different vowel, the order is always I A O. Bish bash bosh. So politicians may flip-flop, but they can never flop-flip. It’s tit-for-tat, never tat-for-tit. This is called ablaut reduplication, and if you do things any other way, they sound very, very odd indeed.’ From ‘The Elements of Eloquence’ by Mark Forsyth.

@MichaelPryor @negativeprimes Of course there ARE some teeny-tiny exceptions.
@cthellis @MichaelPryor @negativeprimes
If you think of it as mouth shape when you are saying the vowels, I A O (as in bish bash bosh) is moving forwards.
EE EYE OH (as in Old McDonald) also does.
Fee Fi Fee Fi Fum (Jack and the beanstalk) also.
@huxley @MichaelPryor @negativeprimes Pretty interesting. I suspect any that go the other way (such as “moon man”) are driven by grammatical forcing.
@cthellis @MichaelPryor @negativeprimes
Maybe that's why 'man in the moon' is so poetic.
