Inscriptional Pahlavi is a script used to write the Middle Persian language. It was used during the Sasanian Empire (224-651 CE). The script is derived from the Aramaic alphabet and is written from right to left.
Inscriptional Pahlavi was used to write a variety of texts, including religious, administrative, and literary works. A large number of inscriptions in this script have been found at sites throughout the Sasanian Empire, including at Persepolis and Naqsh-e Rustam.
The script consists of a number of different characters, each of which represents a different sound. In addition, there are a number of ligatures, or combinations of characters, which are used to represent certain sounds.
Inscriptional Pahlavi is a relatively simple script to learn, and it is possible to read and write it with a limited knowledge of the Aramaic alphabet.
