There are two primary dialects of Bukiyip Chamaun-Yabonuh and Ilipeim-Yamil and two minor dialects Buki and Lohuhwim. Given significant variation among dialects, linguist Robert Conrad suggests that Bukiyip is likely part of dialect chain that also involves other Arapesh languages. The dialects may be further generalized as Coastal Arapesh and Mountain Bukiyip.
