Determiners
Ilokano has two subsets of determiners. Articles are similar to "the" and "a" or "an" in English. Demonstratives are point out something ("this" or "that"), whether what is being referred to is in space, in time or is something previously mentioned.
Ilokano determiners have only two cases (core and oblique)—unlike Ilokano pronouns, which have three: absolutive, ergative and oblique. The core case may function as absolutive or ergative.
