Is barely worth nickels and dimes I don't want this to develop into a punch-up but shurely "assonance" means getting the rhyme right. Did you mean "dissonance", as Google might patronisingly ask.
It doesn't make centsMy dictionary gives 'assonance' as 'partial correspondence; rough similarity', so Botherer is right about that, even if he doesn't know how to use apostrophes. *evil grin*
