Parsi has been used as a name for several languages of South Asia and Iran, some of them spurious:
Parsi, an alternative spelling of Farsi, the Persian language.
Parsi, the variety of Gujarati spoken by the Parsis of Gujarat and Maharashtra in India. Prior to 2023, Ethnologue treated it as a separate language, with the ISO 639-3 code [prp]. That code has now been deprecated and the variety is instead subsumed under Gujarati.[1][2]
Parsi-Dari, a supposed language spoken by Zoroastrians in Iran. Ethnologue assigns it the ISO 639-3 code [prd], but Glottolog considers it spurious and a duplicate of the Zoroastrian Dari language [gbz].[3]
Parsi, a name occasionally used by speakers of Indo-Aryan languages of northern India to refer to speech forms they do not understand. It has been attested, among others, for Santali[4] and Mal Paharia.[5] It has frequently been used in reference to the secret languages of some social groups,[4] for example that of the Bazigar people of north-west India.[6]
