This article explores conceptions of the Malaysian ethnic system from the perspective of certain Bidayuhs, an indigenous group of Sarawak, Borneo. Recent scholarship has highlighted the 'fluid' and 'shifting' nature of Malay identity; but less attention has been paid to how ethnic minorities in the region depict Malayness. I suggest that for many Bidayuhs, Malay-ness is marked by an inescapable flxity which stifies a fluidity that they value as intrinsic to Bidayuh-ness and other aspects of life. Moreover, this sense of flxity has been mapped onto their conceptions of the (Malay-dominated) Malaysian ethnic system, in which they are inescapably entangled. The article investigates some of the consequent tensions arising from Bidayuh (dis)engagements with Malaysia's ethnic 'flxity', while tracing certain trends and changes in this relationship.
