p. 54-6. A verbal reflexive marker –θət, replacing the object marker., which is used when object is coreferential with the subject. In (derived applicative) ditransitives, S cannot bind T argument in a reflexive construction, since T is oblique rather than object; cf. the ungrammatical (85) p. 113; ‘I gave it to myself’. But apparently if A cannot bind T here, either (no examples give though). p. 181. There is however a special construction (called “object cancellation”) for reflexive R/Ben arguments: it involves the use of intransitive marker following the applicative, SEE (124) ‘I baked myself bread’.
