I’saka has fairly strict Subject–Object–Verb word order for declarative sentences. Personal pronouns have Unmarked, Nominative, Accusative and Possessive case forms. The Nominative case pronouns are used for the subjects of transitive and intransitive verbs, the accusative pronouns for the objects of transitives. Pronouns in oblique roles take the Unmarked case form. The Unmarked case forms can also be used in place of Nominative and Possessive pronouns, but the significance of the choice is not clear. Nouns do not have case marking in core grammatical roles, although there are suffixes for Instrumental, Accompaniment/Location and Predicate possessor.
