Tabaru language

Tabaru is a North Halmahera language of Indonesia.

Vowels
Tabaru has a simple five vowel system: a, e, i, o, u.

Syllable structure and stress
On the surface level, Tabaru only allows syllables of the type (C)V. Words with an underlying final consonant add an echo vowel: ngówaka (/ngowak/) ′child′, ókere (/oker/) ′drink′, sárimi (/sarim/) ′paddle′, ódomo (/odom/) ′eat′, pálusu (/palus/) ′answer′. The echo vowel is dropped when a suffix is added: woísene (/woisen/) ′hear′, but woisenoka (/woisen/ + /oka/) ′heard′. Stress regularly falls on the penultimate syllable, but shifts to the antepenultimate when the word takes an echo vowel.
