Again, Malimiutun Iñupiaq is used as a representative example in this section. The basic structure of the verb is [(verb) + (derivational suffix) + (inflectional suffix) + (enclitic)], although Lanz (2010) argues that this approach is insufficient since it "forces one to analyze ... optional ... suffixes". Every verb has an obligatory inflection for person, number, and mood (all marked by a single suffix), and can have other inflectional suffixes such as tense, aspect, modality, and various suffixes carrying adverbial functions.
