Merap (Mbraa) is an Austronesian language, spoken in the village of in South Malinau district, Malinau Regency, North Kalimantan, Indonesia. Soriente (2015) classifies Mbraa (also known as Merap) as a KayanâÂÂMurik (Modang-Bahau) language.
Merap phonology has departed significantly from Proto-Malayo Polynesian. Merap stress is word-final, and word shape is sesquisyllabic (a minor penultimate syllable followed by a stressed full ultima). The number of vowel contrasts has increased significantly as well. Where Proto-Malayo-Polynesian had four vowels (*i, *u, *a, and *ÃÂ) Merap has well over twenty contrasts, including diphthongs, triphthongs, and nasality distinctions.
