Rhymes are sometimes classified into the categories of "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 "tu" with "vu" 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). Authorities disagree, however, on exactly where to place the boundaries between the categories.
