The complementizer strategy depends on the verb. For the 'think' (rekin) verb, no complementizer is used.
Dat karu-ngku im rekin dat mukmuk bin kayikayi im.
[the kid-ERG 3SG think the owl PST chase 3SG.OBJ]
'The kid thought the owl was chasing him.'
For the 'know' (nou) verb, the complementizer wen is used.
