The Avestan ī̆šti- in Middle Persian texts

Abstract

Middle Persian translations and interpretations of Avestan texts employ the word īšt in the translation of the Avestan ī̆šti- “capability, capacity, competence”. The word became a vocabulary item in the Middle Persian corpus. It seems to be a calque of its Avestan counterpart. The Avestan ī̆šti- has presented challenges in the Avesta scholarship and is translated with words from different semantic domains. This article discusses the definition of Avestan ī̆šti- and how it is reinterpreted and understood in the Middle Persian translations. It is argued here that Av. ī̆šti- refers to “capability, capacity, and competence”. However, it is understood and interpreted in the MP texts as “wealth, property”, “remuneration”, or “reward”. It is sometimes translated to a verb form from xwāstan “desire, want”.
