The Kathuran Language (ܠܫܢܐ ܟܬ݁ܘܪܝܝܐ Leššānā Kaṯuryāyā), also known as Church Cildanian, is an ancient Qedarite (Semitic) language, originally spoken in the Barmenian provinces of Arakhim and Kathuristan. In the Middle Ages Kathuran was the official language of the Kingdom of Arakhim, and the language became the vehicle of Qedarite Hosianism and culture, spreading across the continent of Majatra and as far as Aldegar. When Cildania adopted Kathuran-rite Hosianism during the Middle Ages, Kathuran became strongly associated with Cildania, to the point that the language is commonly referred to as "Church Cildanian". Although Kathuran is spoken by a small minority, it remains the liturgical language of several Apostolic Hosian Churches.
