I'm curious about the rhyming in Russian poetry. Latin poetry doesn't rhyme (it's defined almost entirely by the patterning of long and short syllables; word stress exists in Latin but isn't relevant to poetic meter), and my Latin teacher explained this by reference to the fact that, Latin inflection being what it is, it would be extremely easy to rhyme. So easy, apparently, that nobody ever even tried.

It is my impression that Russian is heavily inflected in much the same manner as Latin. So - do Russians feel that certain rhymes are "cheap" or otherwise unworthy? Is it common in poetry to rhyme e.g. one verb form with an identical verb form in the rhyming line, or one noun case ending with the same noun case ending? Any distinction between "high" poetry and vulgar or vernacular poetry?

(For what it's worth, my instincts for English poetic rhyming are:

- Rhyming a word with itself is Poor Form. It's still Poor Form if you rhyme a word with a homonym of itself.

- Rhyming an inflectional suffix with itself doesn't work in the terms I just stated. The suffix is free to participate in a rhyme, but it can't supply the entire rhyme. So rhyming "being" with "seeing" is fine, because "be" and "see" rhyme and it's permissible to continue that rhyme into "being" / "seeing", but rhyming "being" with "doing" can't be done, even though -ing and -ing are the same syllable.)
