Genitives apply to specific objects and immediately follow the objects they apply to.
All other indirect objects apply to the entire clause and go at either the end (after the direct object) or beginning (before the verb) of the clause.
Non-genitives can be made to modify specific objects with the particle "na," which translates roughly, "that is." "Na" preceeds the preposition and immediately follows the object that the indirect object applies to.
Isan dasu napysh ar abad.
Eat mouse cheese(dir-obj) at floor.
The mouse eats the cheese on the floor. (The whole thing takes place on the floor)
Isan dasu napysh na ar abad.
Eat mouse cheese(dir-obj) that-is at floor.
The mouse eats the cheese that is on the floor. (The location of the cheese is being specified)
Isan dasu na ar abad a napysh.*
Eat mouse that-is at floor dir-obj cheese.
That mouse that is on the floor eats the cheese. (The location of the mouse is being specified)
* The direct object preposition "an," which is often dropped, is put back in in this sentence to avoid confusion, since the direct object isn't immediately following the subject.
