The Atlas of the Languages of Iran (ALI) brings together insights from linguists in Iran and internationally, statistical and demographic publications by national agencies, and, foundationally, speakers of the many languages and dialects of the country. Rather than communicating a single view of Iran’s languages and dialects, the Atlas allows users to enrich their own perspectives on language distribution with location-based language data.

The searchable maps highlight patterns in the phonology (the sounds of language), morphosyntax (grammar) and lexicon (words) of Iran’s languages. Users can access, contribute and comment on language data, which are organized in reference to each of the country’s some 60,000 towns and cities.
