P. 629
The auxiliary verb uruleru can be replaced either by Vinf .nonpast koto ga
dekiru or by rareru, except when the verb is totally non-controllable, such as
okiru 'to take place' or aru 'to exist,' as in Exs.(a) and (f).
Since the basic meaning of uruleru is the existence of possibility (not abil-
ity), it cannot be used in a sentence that expresses pure ability as shown in
PI.
(ekoto ga dekiru (DBJG: 200-01); rareru2 (DBJG: 370-73))
