Sahu (Sa’u, Sahu’u, Sau) is a North Halmahera language. Use is vigorous; dialects are Pa’disua (Palisua), Tala’i, Waioli, and Gamkonora. A fifth dialect, Ibu, used to be spoken near the mouth of the Ibu River.[2]
When preceding /a/, /o/, and /u/, the consonants /d/, /ɗ/, and /l/ become retroflex (/ɖ/, /ᶑ/, and /ɭ/, respectively). The trill /r/ alternates freely with /ɾ/, but, according to Visser and Voorhoeve, /r/ is the more usual allophone. The glottal /h/ may be realized as /χ/ by educated speakers for certain words deriving from Arabic.
