Verstraete and Rigsby (2015) determined that Ayabadhu and Yintyingka, spoken by the Yintyingka and Lamalama and previously known as coastal Ayapathu, are closely related and dialects of the same language.[2]: 51 They also found these dialects to be "structurally different" to Western Ayapathu.[4] The name Yintjinggu/Jintjingga has been used for both Ayabadhu and the neighboring Umbindhamu language.[1][5]
