In
http://www.lojban.org/tiki/BPFK+Section:+Causation+sumtcitaIt is proposed that {to'e ri'a} mean "prevented by", while {to'e ri'a nai} mean "despite".
I am confused. If the referent of the tagged sumti prevents the event described by the bridi, which event is there for the main brid to refer to?
The page doesn't give examples. What would them be, if any?
To me, "preventing" is just "causing a negation".
