The present study mainly aims to describe the mechanics of causative-inchoative alternation in modern Persian as well as the causative structure of its verbal system. In this scope, we provide a brief description of the phrase structure of the modern Persian and discuss its main causative-inchoative codification strategies: morphological, lexical and analytic causatives. When giving Persian examples, we use the Transcription procedure for Iranian toponymic items implemented by the Iranian National Committee on the Standardization of Geographic names and subsequently adopted and approved by the United Nations in 2012.
