Proto-Polynesian had five vowels, /a//e//i//o//u/, with no length distinction. In a number of daughter languages, successive sequences of vowels came together to produce long vowels and diphthongs, and in some languages these sounds later became phonemic.[3]
The following is a table of some sample vocabulary as it is represented orthographically in various languages.[4] All instances of ⟨ʻ⟩ represent a glottal stop, IPA /ʔ/. All instances of ⟨ng⟩ and Samoan ⟨g⟩ represent the single phoneme /ŋ/. The letter ⟨r⟩ in all cases represents voiced alveolar tap /ɾ/, not /r/.

^Archaic: the modern Tahitian word for two is piti, due to the practice of pi'i among Tahitians, a form of linguistic taboo. However, the cognate remains in the second-person dual pronoun ʻōrua, roughly translated you two.
