Besides the trivial examples like: le jei ti blanu cu du li pibimu The extent of truth of "this is blue" is 0.85 which I suppose nobody would ever want to use, {jei} doesn't seem to be all that relevant to fuzzy usage. What could be useful would be a way of assigning some truth scale to what is being said, not to some quoted sentence. There are (at least) two ways to do this. One is to use tanru with {mutce}, {traji}, etc. You can't ask for more fuzziness than tanru. Another way is to use attitudinals, for instance the scale: ju'ocai absolute certainty ju'osai ju'o ju'oru'e weak certainty ju'ocu'i uncertainty ju'onai impossibility Adding that to a sentence is somewhat like giving it a fuzzy truth value. So I can say {ju'osai ti blanu} "This is ceratinly blue", or {ju'oru'e ti blanu} "This is blue, I suppose". But I don't see how {jei}, or {ni}, can be put to use for any of this. Jorge
