Hateruma uses morphology and suffixation in its verbs and adjectives. Derivational morphology expresses causative and passive forms in verbs; potential forms are equal to the passive form. Verbal inflection expresses two types of indicatives, an imperative form, as well as a cohortative and prohibitive ending. Adjectives, nouns and verbs also compound and reduplicate, especially in producing adverbs from adjectives.
