The Mualang language belongs to the Ibanic languages branch along with other Ibanic dialects such as Kantuk, Bugao, Desa, Seberuang, Ketungau and Sebaruk. These dialects mainly differ from one another in their pronunciations of specific phonemes. For example, words that end with "i" can be pronounced as "e" or "y" where "kediri" becomes "kedire", "rari" becomes "rare", "inai" becomes "inay", and "pulai" becomes "pulay". These words still carry the same meaning even though they are pronounced differently. These dialects also have some lexical variation between them.
