I think we've been taking the wrong approach. The way to create an "is an event" selbri in Lojban is to use "nu". "nu co'e kei" avoids specifying the type of event: it's a selbri with place structure "x1 is an event/state/process". The lujvo is "nunco'e". "nunco'e valsi" would lead to a lujvo "nuncomkezvla", or possibly "nuncomvla". -zefram
