Passivization by the passive enclitic ti (A if expressed introduced by the general/oblique preposition kē). Both R and T can be passivized (see 13a-b). NB K&H passivization noncommittal for the distinction of R and T. Note however that the retained object in those cases is introduced by OBL (kē), which means that only the firs object can be passivized: R in a secundative pattern and T in the indirective pattern.
