A study examined the phonological status of laminal sibilants in Chamicuro, a Maipuran Arawakan language spoken in the Amazonian lowlands of eastern Peru. The phonemic inventory of these sibilants shows a very strong symmetry of three affricates and three corresponding fricatives. However, when the laminal alveolar fricative is considered, the…
