(Of course, this is disingenuous, because the typical box (mode) is of course brown --- cardboard. Should have stuck with home cities of Americans.)
I think that by not seizing the liferaft {of interpreting lo'e as either
mode or median}, but allowing ambiguity between the two, you've doomed
yourself to the riptides of eternal jboske.
Watch it! You're trying to give kau a sane and consistent meaning. Which,
of course, collides with the way Jorge and his disciples use it.
For
instance, in that case, makau would mean "I know the value, but I want you
to tell me anyway".
The "known" part is not right. It comes from most examples of {kau} being based on {djuno}, but it is not really part of {kau}. We can say {noda djuno le du'u makau zukte}, "nobody knows who did it", for example, where {kau} obviously does not mean that the value is known. It is not even clear that it need be instantiated.
