Lojban has "ju" for the connective but it left out the corrresponding unary operator. "na na" is logically equivalent to "ni", but it doesn't quite feel right. We need "ni" in order to be able to emphasize affirmation, or contrast it with negation. Whatever the way to emphasize "na" is will probably use the word "na" to stand on, and we need a word to stand on if we want to emphasize affirmation. If we have a short word for "jtfa" surely there must be the corresponding one for "jtna".
OK. I was thinking of the logical operators as selected on grounds of utility -- the brevity they afford -- tho I suppose that even if CV space gets really crowded and in high demand, there's always CVVVV etc. --And.
