Attention, all you poets out there: do you know what this (rime riche) is? I just came across it while looking up something else. I have to say, the pronunciation given bugs me; to me it looks like it ought to be reem reesh. It is apparently similar to identical rhyme, which I confess I thought at first was a redundancy. But I guess not:

Ok--what's the deal with pronunciation, here? I didn't actually read this one until I copied it (at the site, you can see that the e's have the long-e line over them; didn't copy, sorry), because I had just looked at another dictionary which gives rim rish as the pronunciation.
