Verbs, the most complex word class, are inflected for one of three "orders" ("indicative", the default; "conjunct", used for participles and in subordinate clauses; and "imperative", used with commands), as negative or affirmative, and for the person, number, animacy, and proximate/obviative status of both the subject and object as well as for several different "modes" (including the "dubitative" and "preterit") and tenses.
