History: long tanru gotcha
View page
Source of version: 2
(current)
See also ((long tanru)) for another viewpoint. It sounds tempting, if a single brivla or a gismu seems too vague, to make a tanru; and if the tanru is still too vague, to make a more complex tanru. This can often be communicatively effective. But the more components in the tanru, the more semantic ambiguities there are, because each tanru joint introduces one or more ambiguous meanings, and the ambiguities, quite literally, multiply. ''On the other hand, a tanru with 1000 gismu should be pretty specific.'' * But it would be devlish hard to figure out what it specified, with say 3^1000 possible readings. The final defense is to make a new lujvo and nail down its meaning. (This is if you think one can only communicate using semantically exact utterances. Whereas I insist that most human usage differs from this, in that there is much assumed meaning taking place, and then each utterance modifies the context in a minimalistic way. In essence, the course of the ball both teams are playing with, gets nudged this way or that; what utterances mark is the ''change'' in direction. Therefore ''tanru'' are perfectly adequate for everything except the formal discourse of philosophers and scientists... but don't let me keep ''you'' from taking twenty five Lojban words to order a cup of coffee!) ---- *This may be true in theory, but in practice ((tanru)) parts generally have a very close relationship to one another, quite often one of the officially possible relationships for ((lujvo)). Also, there are informal conventions for many gismu concerning how they are used in ((tanru)). For example, ''xunre'' as ((seltau)) is almost certainly symmetric. *Practically, an on-the-fly ((lujvo)) doesn't help the situation, because in order to decode a ((lujvo)), you still have a couple of possible meanings for each joint (which multiply), and you have to work out the unified place structure, which you don't have to do if you leave it as a ((tanru)). If you leave out ''ke''s and ''bo''s in your ((lujvo)) or even leave out complete ((gismu)) ((Zipf's Law|zipfeanly)), then the ((lujvo)) quickly become at least as hard to decifer as a monster ((tanru)). If you're really worried about this, the solution is to use ((Gismu Deep Structure|unambiguous structures)) and avoid ((tanru)) and ((lujvo)) altogether. -- ((Adam)) ''In actual communication, which almost always occurs between who share a universe of discourse, there are but so many ideas that can be comprehended; the universe of discourse is of finite extent in a hypothetical space of concepts. So while a long tanru might select a huge number of concepts, all the tanru really needs to do is "space apart" the [[members of the set of] possible interpretations such that only one is within the universe of discourse (the others are meaningless jibberish or undiscovered concepts), and also within the context of the discussion! --xod''
