Mongol, also known as Mwakai, is a Keram language of Papua New Guinea.
[4] The sound [t] only occurs in borrowings, with earlier */t/ having historically become /r/; this is belied by the realisation of word-final /r/ as [t~r~l].
/s/ patterns as a palatal consonant, with the optional allophone [ʃ]; there is some interplay between the sounds /s/ and /ⁿd͡ʒ/ in casual speech, with the contrast sometimes being neutralised in favour or either realisation.
[ɲ] is a marginal phone which appears in borrowings and occasional as a realisation of /n/ before /i/.
/w/ and /j/ have a limited distribution, appearing mostly word-initially or -finally, and only rarely intervocalically.
