"Pahlevi" (often spelled "Pahlavi") refers to the Middle Persian language used in Iran during the Sasanian Empire and the early Islamic period. It's a stage in the evolution of the Persian language, bridging Old Persian and modern Persian. Think of it as the Middle English to modern English. This language is crucial for understanding Zoroastrian texts and other historical documents. The term also refers to the writing system used for this language. Thus, "Pahlevi" represents a specific linguistic and cultural phase in Iranian history.
