/v/ has two allophones: an approximant [ʋ], which appears word-initially, and a fricative [v], which occurs elsewhere.
[14][15] However, there are some cases that disturb that distribution, which shows that the allophony is not only caused by stress but also has a morphological factor: Thus, it appears that the underlying representation of words includes the plosive-fricative distinction.
[16] The sequences /sj, zj/ coalesce to [ɕ, ʑ], unless /j/ occurs as a part of the rising diphthongs /jɪ, jɛ, jø/.
[42] That view is supported by Hoekstra & Tiersma (2013) who transcribe them with consonant symbols /jɪ, jɛ, wa, wo/,[43] which is the convention that is used in this article.
According to Booij, the glide behaves as a consonant in such sequences since it is shifted entirely to the next syllable when a following vowel is added.
