Mathnawi (Arabic: مثنوي mathnawī) or masnavi (Persian: مثنوی) is a kind of poem written in rhyming couplets, or more specifically "a poem based on independent, internally rhyming lines". Most mathnawī poems follow a meter of eleven, or occasionally ten, syllables, but had no limit in their length. Typical mathnawi poems consist of an indefinite number of couplets, with the rhyme scheme aa/bb/cc.
