last bridi (with its modifiers)
Repeats the immediately preceding bridi as "go'i" does but with all of the modifiers made in the same, particularly negations/affirmations, excluding "xu". All referents remain the same unless they are explicitly changed or restated, or the word "ra'o" is used. If the previous bridi (say, a true-false question) were phrased in the negative, then this word would answer in the negative (whereas "go'i" would answer in the positive), and "nago'ai" would answer in the affirmative (whereas "nago'i" would answer in the negative). This word nontrivially couples with "nei'ai" in the case of the referent bridi being phrased negatively. Subscripting this word with an integer n causes the referent sentence to be earlier than the current bridi by exactly a count of n; n = 0 implies reference to the current bridi, n = +1 implies reference to the immediately preceding bridi (this is the default), n = -1 implies reference to the immediately subsequent bridi, n > 0 implies reference to some previously uttered bridi, n < 0 implies reference to some future bridi.
