Nouns
Nouns in Proto-Piduru are either animate, marked with the suffix -są, or inanimate, marked with the suffix -ku. The plural is formed by removing the animacy suffix. Noun with a plural form do not take any animacy marking in the singular.

Inalienable possession is indicated by agreeing with the animacy of the possessor. For example:


 * maųsą bųsąkiñ — the cat's head
 * rawaku bųkubam — the top of the mountain

Cases
Nouns are inflected for 11 cases: subjecive, ergative, accusative (-ba), inessive (tim-), allative (niñ-), ablative (rin-), instrumental, comitative, causative, essive and derivational (-im).

Verbs
Verbs are polypersonal and conjugated for subject, direct and indirect object, tense, aspect and mood. The person prefixes are the same regardless of function, instead, distinguished by position. The subject prefix precedes the direct object, which in turn precedes the indirect object.

Direct objects may be incorporated into the verb with the derivational affix. For example:


 * Yikuñ maųba. — I eat cats.
 * Yimaųįkuñ. — I cats-eat.
