In a language with some verbs triggering quirky case on the object, under certain circumstances if the object is missing the case suffix/clitic goes somewhere else in the sentence. The circumstances that trigger this are:
- objects being topicalized
- objects only being present as congruence marking on the noun
- objects having certain determiners on them that prevent the case markers
In these cases, the case marker tends to appear on whichever is the rightmost of:
- adjectival complements (esp. object complements)
- indirect objects
- subjects
- a dummy pronoun
