The rime pauvre is the minimal acceptable unit of rhyme in classical French versification, consisting of the correspondence of the tonic vowel alone between the rhyming words, without any additional consonantal agreement. Classical theorists considered it barely adequate and advised poets to seek richer correspondences. However, poets have exploited the pauvreté of poor rhymes expressively, using their thinness to create effects of emptiness, melancholy, or deliberate anti-ornament. Modern and free verse poets use near-rhyme and rime pauvre as alternatives to the richer sonic patterning of classical verse, maintaining sonic suggestion without the full closure that rich rhyme creates.

Rime pauvre is the most minimal traditionally acceptable French rhyme, based on a shared final vowel sound alone. While technically weaker than richer rhymes, it is not automatically inferior in artistic effect, since poets may choose simpler rhyme deliberately for tonal restraint or structural variation. Students should compare with rime suffisante, rime riche, and rime léonine. French poetic criticism historically pays unusually close attention to rhyme quality, making such distinctions important for formal analysis. Understanding rhyme hierarchy helps decode historical aesthetic expectations.
