Does «duatūa» require the third argument to be true?

[acotis]

It has been said that duatūa == tua dủa — I think it was Hoemai who said this but it was a long time ago and I couldn't find the message. If this is the case then the duatūa-3 must be true, and you can't use the word to mean "he told me he was six feet tall" if the person in question isn't six feet tall.

There is also the question of whether the duatūa-2 is required to believe the proposition. If truth is not required but believe is, then chıtūa might be a better spelling. If neither is required, then perhaps rủaq + còu is appropriate. (còu is experimental, and is proposed as a predicate by Liq and as a poi-like by me.)

[xorxes]

tua bo dao might be another possibility. chitua doesn't sound right for this.
