Maharashtri Prakrit, the ancestor of modern Marathi, is a particularly interesting case. Maharashtri was often used for poetry and as such, diverged from proper Sanskrit grammar mainly to fit the language to the meter of different styles of poetry. The new grammar stuck, which led to the unique flexibility of vowels lengths – amongst other anomalies – in Marathi. Marathi retains the original Sanskrit pronunciation of certain letters such as the "anusvāra" (for instance, "saṃhar," compared to "sanhar" in Hindi). Moreover, Marathi preserves certain Sanskrit patterns of pronunciation, as in the words "purṇa" and "rāma" compared to "purṇ" and "rām" in Hindi.
