text affirmation/negation mode toggle
Until the next utterance of this word, the interpretation of all following (but not preceding) negations and affirmations are to be re-interpreted bridi-by-bridi, starting with the current open (not-yet-terminated) bridi (in which this word is uttered). If this word is followed by a number of/evaluated to a value 0 or 1 (preceded immediately by "li"), this value is taken to be an explicit reset of the mode to the value indicated (the value in question is called a seed value). Iff the seed value is 1, the mode is set thereinafter to multiplicative style; iff the seed value is 0, the mode is set thereinafter to additive style. (That is: the seed values represent the identity elements under the operation which the mode emulates.). No other value, numerical or otherwise (including other sumti or even Boolean values, which actually mean "truth" and "false", rather than "1" and "0" respectively, despite common representations), may act as a seed value of this word. Thus, only in the context of this word being followed by a "li"-introduced mekso expression X which evaluates to the numbers 0 or 1 wherein X is not intended to be taken as a seed value of this word must this word be followed by ku prior to X; in this case there is no explicit seed value. If this word has no explicit seed value, then this word causes the mode of interpretation of double-negatives to switch between multiplicative style and additive style; an utterance of this word switches the mode to whichever of these two options was not being used immediately previously. Thus, it is its own terminator/negator. Lojban default (without context) is in multiplicative mode: "mi na na nelci" is nearly equivalent to "mi nelci"; double-negatives cancel leaving a positive sense (even if it is not entirely/definitively affirmative). So, one utterance of this word (under standard conventions) in a given discourse will change double-negatives to become additive. This mode is similar to (some) Spanish negation or AAVE negation; multiple negatives compound/add together, intensifying the negativity (subjective truth-value) of an utterance. In additive mode, "[zau'e'u] mi na na nelci" is equivalent to "mi ba'e na nelci" or something of the like; "[zau'e'u] mi na na na na nelci" would be simply further emphasized (roughly twice as emphatic as the previous example's negation). This word is intended mostly for stylistic purposes and translations, as well as enabling further cultural neutrality. lai .krtisfranks. requests that this word (and all of its relevant information, including the selma'o label) be mapped to "zau'eu" if the string "eu" ever becomes officially accepted in Lojban.
