The Gorontalo language (also called Hulontalo) is a language spoken in Gorontalo Province, Sulawesi, Indonesia by the Gorontalo people.
Musa Kasim et al. (1981) give five main dialects of Gorontalo: east Gorontalo, Limboto, Gorontolo City, west Gorontalo, and Tilamuta.
Consonant sequences include NC (homorganic nasal–plosive), where C may be /b d t d̠ ɟ ɡ k/. Elsewhere, /b d/ are relatively rare and only occur before high vowels. /d̠/, written ⟨ḓ⟩ in the literature, is a laminal post-alveoral coronal stop that is indeterminate as to voicing. The phonemic status of [ʔ] is unclear; if [VʔV] is interpreted as vowel sequences /VV/, then this contrasts with long vowels (where the two V's are the same) and vowel sequences separated by linking glides (where the two V's are different).
Gorontalo has five vowels.
