===Complex sentences and coreferentiality===
The three most common means of joining [[clause]]s are sentence-sequence (juxtaposed clauses that have separate intonation contours),{{sfn|Tsunoda|2011|p=439}} [[Coordination (linguistics)|coordination]] (juxtaposed clauses with one intonation contour and sharing of conjugational categories such as tense){{sfn|Tsunoda|2011|p=438}} and [[Subordination (linguistics)|subordination]]. The most common type of subordination is the purposive.

If there are shared arguments, they are more likely to be deleted from the second clause if it is subordinate, and least likely if it is sentence-sequence.{{sfn|Tsunoda|2011|p=443}} The restrictions on the [[syntactic function]] of the shared argument are typical of [[Syntactic ergativity|syntactically ergative]] languages. The shared argument has to have the same function in both clauses, or be an intransitive subject (S) in one and a transitive patient-like argument (O) in the other:{{sfn|Tsunoda|2011|loc=p. 418, table 4-13}}
{{interlinear|indent=3
|bama-nggo warrngo mayga-n yani-yal{{sfn|Tsunoda|2011|p=423}} 
|man-ERG woman.ABS tell-NF go-PURP
|"The man told the woman to go." (main clause O coreferential with deleted S of the subordinate clause)}}

In case the shared argument is a transitive agent-like argument (A) in one of the clauses, [[Antipassive|antipassivisation]] will be involved. It is signalled by a verbal suffix and affects the case marking of the arguments of this verb. In comparison with the basic verb, which marks the A with ergative/nominative and the O with nominative/accusative, the antipassivised verb marks the A with nominative and the O with either ergative or dative.{{sfn|Tsunoda|2011|p=427}} The agent-like argument then becomes available to be coreferential with a patient of a transitive verb or a subject of an intransitive one:
{{interlinear|indent=3
|gorngga-do birgo mayga-n wajo-gali-yal{{sfn|Tsunoda|2011|p=446}} 
|husband-ERG wife.ABS tell-NF cook-ANTIP-PURP
|"[The] husband told [his] wife to cook." (main clause O coreferential with A of subordinate clause, therefore antipassive is necessary)}}
