x [x]: voiceless velar fricative
Word: bixis [pɪxɪs] “its pus"
Description: The voiceless velar fricative x [x] is in stem initial position, intervocalic, and preceded by the 3rd person singular pronoun bi [pɪ].
Young and Moran use the letter ‘h’ to represent different sounds. They also use the ‘h’ letter to represent this velar fricative sound in stem initial position. Thus this word [pɪxɪs] can also be spelled ‘bihis’ [pɪxɪs]. In the prestem complex or at the end of a syllable, this letter ‘h’ represents a glottal fricative [h], see the H sound.
