Consider (8) and 11 On the assumption made above that -se is an exponent of an applicative head that introduces a recipient argument, the subject arguments in (20) and (21) are introduced as underspecified: the one in (20) can be interpreted agentively or nonagentively, but the one in (21) can only be interpreted agentively in the presence of a recipient argument.
the possibility of co-occurrence of an agent and a non-agent can be reduced to the availability of the applicative morpheme -se.
