title: The evolution of Action Nouns in &lt;em&gt;-išn&lt;/em&gt; between Middle Persian and New Persian
abstract: Middle Persian Action Nouns in -in have become -e in Standard Contemporary Persian. In Early New Persian (8th-12th centuries), there are some occurrences of -in. The present paper focuses on the evolution of these words, especially ravin "method" in the name of the vizier Rst-Ravin in the Siysat-nma "The Book of Government" by Nizm al-Mulk, which was reinterpreted as Rst-Rauan.
