Some analyses present /tʃ/ as an eighth phoneme,[6] although its distribution is predictable. [tʃ] and in some cases /r/ are positional variants of /t/, as described in the table below.[5]
Word-initially [r] may be heard in place of expected [t] in rapid speech if the previous word ends in a vowel. In no environment do more than three phonemes contrast, meaning that a fourth oral coronal /tʃ/ is not required. [tʃ] only occurs following high vowels /i/ or /u/ (e.g. [putʃwapu] 'lazy') where it can be seen as an allophone of /t/. In most environments only two phonemes contrast, suggesting that /r/ only recently diverged from /t/.
The glides [j w] occur as allophones of /i u/, e.g. /iapu/ [japu] 'Sepik river', /uəla/ → [wəla] 'house'.[5]
Grammar
Unlike other Sepik languages, Namia has an inclusive-exclusive distinction for the first-person pronoun, which could possibly be due to diffusion from Torricelli languages.[6] Inclusive-exclusive first-person pronominal distinctions are also found in the Yuat languages and Grass languages.
