Rime riche
Rime riche is a form of rhyme with identical sounds, if different spellings.
In French poetry, unlike in English, it is common to have "identical rhymes", in which not only the vowels of the final syllables of the lines rhyme, but their onset consonants ("consonnes d'appui") as well. To the ear of someone accustomed to English verse, this often sounds like a very weak rhyme. For example, an English rhyme of homophones, flour and flower, would seem weak, whereas a French rhyme of homophones doigt and doit is not only acceptable but quite common.
Rhymes are sometimes classified into the categories "rime pauvre" ("poor rhyme"), "rime suffisante" ("sufficient rhyme"), "rime riche" ("rich rhyme") and "rime richissime" ("very rich rhyme"), according to the number of rhyming sounds in the two words or in the parts of the two verses. For example to rhyme "parla" with "sauta" would be a poor rhyme (the words have only the vowel in common), to rhyme "pas" with "bras" a sufficient rhyme (with the vowel and the silent consonant in common), and "tante" with "attente" a rich rhyme (with the vowel, the onset consonant, and the coda consonant with its mute "e" in common).
