I'm not sure how much conlang wants to go into this, which seems to get asked every year or two. An example where they have copied our solution: The vocative for self identification (mi'e/Hue), and I believe they have also moved in our direction on vocative grammar as well (more free use of vocatives was actually a Jim Carter invention rejected by JCB). Nora found a bug in the lujvo/complex-word-making algorithm, which I have now heard that they solved in a similar way after we told them about it. Things they haven't fixed: negation - they have only one negation word and it is ambiguous between contrary and contradictory negation, though certainly with a more contradictory bent. They also have scope problems with negation. scope of abstraction - their event abstractor "po" = Lojban "nu" changes the meaning of a predicate rather than abstracts a predication into another predicate. They have a "lepo" that abstracts a predication into an argument, and the "lepo" "le po" distinction is grammatical, which we considered a violation of audio visual isomorphism. tense - JCB used simple tenses in combination to form things that resemble perfectives but are ill-defined. There is no published tense grammar at all - at the time of the split, anything including non-tense stuff could be stuck on the end of a tense word and it was grammatical. MEX - they have no grammar of mathematical expressions but recognize the need for same. sumti raising - they have not addressed this issue, which for non-loglangers is the difference between "I closed the door" and "I was the agent in the door becoming closed", or between "I finished the dinner", and "I finished eating the dinner" or "I finished cooking the dinner" or between "I know Lojban", and "I know Lojban is a logical language". In each case an abstract sentence/predicate is concealed in an object in the shorter sentence. They use English idiomatic conventions in making compounds - especially using the word madzo (to make y out of z) in causal compounds (e.g. "finish" = "whole-make", "farm (vb)" ="grow-make"). Other examples include the infamous "man a ship" = "man-do". Lojban has swung to the other extreme, with a tendency to avoid metaphorical compounds completely - probably not a bad idea while usage is dominated by English native speakers. There are many others, but it gets technical. But these are all things that we have solved. lojbab ---- lojbab Bob LeChevalier, President, The Logical Language Group, Inc. 2904 Beau Lane, Fairfax VA 22031-1303 USA 703-385-0273 Artificial language Loglan/Lojban: (newly updated!)
