Either the first or the second vowel will be treated as a semivowel.
The combination of semivowel plus vowel e.g. [je] is a rising diphthong.
A semivowel is a gliding sound in which the speech organs start at or near a close vowel and immediately move away to some other vowel.
The question immediately arises as to how these semivowels are sequenced with respect to other vowels, and also, more generally, the question of sequencing of vowels within monosyllables.
This language manifests a pattern of regressive nasalization in which nasality spreads from a nasal consonant over a nasal span that includes vowels, semivowels and laryngeal glides.
There were no monophonemic long vowels nor diphthongs, though sequences of vowel and semivowel within a single syllable (such as j) could exist.
The palatal stop may be realized as a semivowel.
The semivowel /w/ and the palatalised dental spirant /y/, in general, regularly reflect f and s, respectively.
