The Roshan area is located in the northern part of the Shighnan District, in the Badakhshan Province of Afghanistan.[what about Tajikistan?] Roshan consists of six villages, five of which are located on the bank of the river Panj, which meets[clarification needed] at the border of Tajikistan. Most Rushani speakers belong to the Ismaili branch of Shi'a Islam.
Rushani, like other Shugni dialects, is only used in unofficial settings. All of the children in the community learn Rushani as their first language and rely heavily on it until they enroll in school. It is only then that they learn the official language of the country. Adult speakers are all bi- or tri-lingual in Tajik and Russian. The language is not written; Rushani speakers write in Tajik.
Rushani is unusual in having a transitive case – a so-called double-oblique clause structure – in the past tense. That is, in the past tense, the agent and object of a transitive verb are both marked, while the subject of an intransitive verb is not. In the present tense, the object of the transitive verb is marked, the other two roles are not – that is, a typical nominative–accusative alignment. See transitive case for examples.
