The labiodental nasal is realized as [ɱʷ] before /a/ and as [ɱ] before /i/ and /e/; Paulian (1975) suggests that this is due to a conflict between labialization and the spread front vowels.
The velar stop is [k] word initially and typically [ɡ] between vowels; there is a similar alternation with [t] and [ɾ].
Cw sequences are rare and only occur before unrounded vowels; they include /tw/ [tɕɥ], /sw/ [ɕɥ], /ndzw/ [ndʒɥ], /jw/ [ʑɥ], /kw/ [kɥ].
It may be possible that the frequent sounds [pf, bv, ɱʷ] (which occur before /i a u, i e a u, i e a/, respectively) are phonemically /pw, bw, mw/, but Paulian (1975) argues against this analysis.
It may be possible that the frequent sounds [ts, dz, ɲ] are phonemically /tj, dj, nj/, but they are not restricted as to following vowels and Paulian (1975) argues against this analysis.
Roots (not counting nominal prefixes and the like) are of the forms CV, CVV, CVCV, CVVCV, and CVCVCV.
