Editing Hadza language (section)

===Vowels===
Hadza has five vowels, {{IPA|[i e a o u]}}. Long vowels may occur when intervocalic {{IPA|[ɦ]}} is elided. For example, {{IPA|[kʰaɦa]}} or {{IPA|[kʰaː]}} 'to climb', but some words are not attested with {{IPA|[ɦ]}}, as {{IPA|[boːko]}} 'she' vs {{IPA|[boko]}} 'to be ill'. All vowels are nasalized before glottalized nasal and voiced nasal clicks, and speakers vary on whether they hear them as nasal vowels or as VN sequences. Invariable [[nasal vowel]]s, although uncommon, do occur, though not before consonants that have a place of articulation to assimilate to. In such positions, {{IPA|[CṼCV]}} and {{IPA|[CVNCV]}} are allophones, but since VN cannot occur at the end of a word or before a glottal consonant, where only nasal vowels are found, it may be that nasal vowels are allophonic with VN in all positions.{{Citation needed|date=May 2023}}
