Usage notes
This term, as well as a handful of other Koryo-mar familial terms, such as and, seem to be used in some Koryo-saram families even after Koryo-mar stopped being transmitted to younger generations, making it some of the few Koryo-mar words that continue to be used among the younger Russian-speaking generations — outside of food and cultural terms.
