Khargi is spoken on the island of Kharg in the Persian Gulf. A member of the Southwest branch of the Iranian languages, Khargi is related to the languages spoken in the province of Fārs and along the coastal line down to the Strait of Hormuz, suggesting extensive maritime contact, yet does not lend itself to any of the known subgroups of the family. As Khargi remains largely obscure, this article offers a morphosyntax and lexical analysis based on published texts and those collected by the author. It investigates the linguistic position of Khargi based on comparative-historical phonology as well as areal features, with a look at cross-linguistic influence in the situation of language contact. By contrasting linguistic findings with details of history and economy, an attempt is made to date the original and later human settlements on the island.1
