lujvo with more than two parts. |
So far, we have concentrated on selecting the places to go into the place structure of a lujvo. However, this is only half the story. In using selbri in Lojban, it is important to remember the right order of the sumti. With lujvo, the need to attend to the order of sumti becomes critical: the set of places selected should be ordered in such a way that a reader unfamiliar with the lujvo should be able to tell which place is which.
If we aim to make understandable lujvo, then, we should make the order of places in the place structure follow some conventions. If this does not occur, very real ambiguities can turn up. Take for example the lujvo ``jdaselsku'', meaning ``prayer''. In the sentence
7.1) di'e jdaselsku la dong.
This-utterance is-a-prayer somehow-related-to-Dong.
we must be able to know if Dong is the person making the
prayer, giving the meaning
7.2) This is a prayer by Dongor is the entity being prayed to, resulting in
7.3) This is a prayer to Dong
We could resolve such problems on a case-by-case basis for each lujvo (Section 14 discusses when this is actually necessary), but case-by-case resolution for run-of-the-mill lujvo makes the task of learning lujvo place structures unmanageable. People need consistent patterns to make sense of what they learn. Such patterns can be found across gismu place structures (see Section 16), and are even more necessary in lujvo place structures. Case-by-case consideration is still necessary; lujvo creation is a subtle art, after all. But it is helpful to take advantage of any available regularities.
We use two different ordering rules: one for symmetrical lujvo and one for asymmetrical ones. A symmetrical lujvo like ``balsoi'' (from Section 5) has the places of its tertau followed by whatever places of the seltau survive the elimination process. For ``balsoi'', the surviving places of ``banli'' are b2 and b3, leading to the place structure:
7.4) b1=s1 is a great soldier of army s2
in property b2 by standard b3
just what appears in Example 5.1. In fact,
all place structures shown until now have been in the correct
order by the conventions of this section, though the fact has
been left tacit until now.
The motivation for this rule is the parallelism between the lujvo bridi-schema
7.5) b1 bansoi s2 b2 b3
b1 is-a-great-soldier of-army-s2
in-property-b2 by-standard-b3
and the more or less equivalent bridi-schema
7.6) b1 sonci s2 gi'e banli b2 b3
b1 is-a-soldier of-army-s2 and
is-great in-property-b2
by-standard-b3
where ``gi'e'' is the Lojban word for ``and'' when placed
between two partial bridi, as explained in Chapter 14.
Asymmetrical lujvo like ``gerzda'', on the other hand, employ a different rule. The seltau places are inserted not at the end of the place structure, but rather immediately after the tertau place which is equivalent to the first place of the seltau. Consider ``dalmikce'', meaning ``veterinarian'': its veljvo is ``danlu mikce'', or ``animal doctor''. The place structures for those gismu are:
7.7) ``danlu'': d1 is an animal of species d2
``mikce'': m1 is a doctor to patient m2 for ailment m3
using treatment m4
and the lujvo place structure is:
7.8) m1 is a doctor for animal m2=d1 of species d2
for ailment m3 using treatment m4
Since the shared place is m2=d1, the animal patient, the
remaining seltau place d2 is inserted immediately after the
shared place; then the remaining tertau places form the last
two places of the lujvo.
