A common pattern, perhaps the most common pattern, of lujvo-making creates what is called a “symmetrical lujvo”. A symmetrical lujvo is one based on a tanru interpretation such that the first place of the seltau is equivalent to the first place of the tertau: each component of the tanru characterizes the same object. As an illustration of this, consider the lujvo balsoi: it is intended to mean “both great and a soldier”- that is, “great soldier”, which is the interpretation we would tend to give its veljvo, banli sonci. The underlying gismu place structures are:
In this case the s1 place of sonci is redundant, since it is equivalent to the b1 place of banli. Therefore the place structure of balsoi need not include places for both s1 and b1, as they refer to the same thing. So the place structure of balsoi is at most
Some symmetrical veljvo have further equivalent places in addition to the respective first places. Consider the lujvo tinju'i, “to listen” (“to hear attentively, to hear and pay attention”). The place structures of the gismu tirna and jundi are:
and the place structure of the lujvo is:
Why so? Because not only is the j1 place (the one who pays attention) equivalent to the t1 place (the hearer), but the j2 place (the thing paid attention to) is equivalent to the t2 place (the thing heard).
A substantial minority of lujvo have the property that the first place of the seltau (gerku in this case) is equivalent to a place other than the first place of the tertau; such lujvo are said to be “asymmetrical”. (There is a deliberate parallel here with the terms “asymmetrical tanru” and “symmetrical tanru” used in Chapter 5.)
In principle any asymmetrical lujvo could be expressed as a symmetrical lujvo. Consider gerzda, discussed in Section 12.3, where we learned that the g1 place was equivalent to the z2 place. In order to get the places aligned, we could convert zdani to se zdani (or selzda when expressed as a lujvo). The place structure of selzda is
and so the three-part lujvo gerselzda would have the place structure
However, although gerselzda is a valid lujvo, it doesn't translate “doghouse”; its first place is the dog, not the doghouse. Furthermore, it is more complicated than necessary; gerzda is simpler than gerselzda.
From the reader's or listener's point of view, it may not always be obvious whether a newly met lujvo is symmetrical or asymmetrical, and if the latter, what kind of asymmetrical lujvo. If the place structure of the lujvo isn't given in a dictionary or elsewhere, then plausibility must be applied, just as in interpreting tanru.
The lujvo karcykla, for example, is based on karce klama, or “car goer”. The place structure of karce is:
An asymmetrical interpretation of karcykla that is strictly analogous to the place structure of gerzda, equating the kl2 (destination) and ka1 (car) places, would lead to the place structure
kl1 goes to car kl2=ka1 which carries ka2 propelled by ka3 from origin kl3 via route kl4 by means of kl5
But in general we go about in cars, rather than going to cars, so a far more likely place structure treats the ka1 place as equivalent to the kl5 place, leading to
kl1 goes to destination kl2 from origin kl3 via route kl4 by means of car kl5=ka1 carrying ka2 propelled by ka3.
instead.
