All of the children in the community learn Rushani as their first language and rely heavily on it until they enroll in school.

Rushani is unusual in having a transitive alignment system – a so-called double-oblique clause structure – in the past tense.

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.
