The Tapan language, spoken in the town of Tapan in southern West Sumatra province, is a recently discovered Malayan language which has been proposed as related to but not part of Minangkabau. Together, Tapan and Minangkabau would form a Greater Minangkabau subgroup.[6] The two languages Tapan and Muko-Muko form a Lunangic subgroup within the Minangic (Greater Minangkabau) language group.[7][8]
