Instrumental.—When an instrument is the remote object of the verb, the accusative remains unchanged, but the instrumental case takes the same suffix as the nominative-agent; thus, mêndu wagan bŭrgandu bume, the man hit a crow with a boomerang. Inarru burumain kunnedu bangabe, the woman cut a dog with a yamstick.
In the above examples, as well as in the sentences illustrating the nominative-agent, it will be seen that the agent suffix has euphonic changes according to the termination of the word it is attached to. This may be said of the suffixes in all the cases of nouns and adjectives.

Adjectives follow the qualified nouns, and are inflected in the same manner for number and case. Buru mununmang, a kangaroo large; burubula mununbula, a couple of large kangaroos; burudyimma munundyimma, several large kangaroos.
Casuative.—Baualga mununga mirri ngubuningga, a man large a dog will beat. The other cases are also declined like the nouns. Frequently one of the affixes, both in number and case, is omitted sometimes the affix of the noun, and in other instances that of the adjective, being thus eliminated, according to the euphony of the expression.
