Since we were on the topic of muffin tops yesterday, it's only natural to move on to midriffs today. Right?
I was sort of surprised to see that midriff is actually a pretty old word in English. It comes from Old English midhrif, which is a compound word from mid + hirf ("mid" + "belly"). Hrif derives from Proto-Germanic *hrefiz-, which comes from Proto-Indo-European *kwrep- ("bodfy, form, appearance"). Notice the similarity between that PIE word and corporeal, corpse, etc? Good eye, they also derive from *kwrep-.
