In expressing a scalar negation, we can provide some indication of the scale, range, frame-of-reference, or universe of discourse that is being dealt with in an assertion. As stated in Section 15.4 , the default is the set of plausible alternatives. Thus if we say:

the pragmatic interpretation is that we mean a different color and not

However, if we have reason to be more explicit (an obtuse or contrary listener, or simply an overt logical analysis), we can clarify that we are referring to a color by saying:

We might also have reduced the pragmatic ambiguity by making the two trailing sumti values explicit (the “as perceived by” and “under conditions” places have been added to the place structure of xunre ). But assume we have a really stubborn listener (an artificially semi-intelligent computer?) who will find a way to misinterpret Example 15.64 even with three specific sumti provided.

In this case, we use a sumti tagged with the sumtcita ci'u , which translates roughly as “on a scale of X” , where X is the sumti. For maximal clarity, the tagged sumti can be bound into the negated selbri with be . To clarify Example 15.64 , we might say:

We can alternately use the sumtcita teci'e , based on ciste , which translates roughly as “of a system of components X” , for universes of discourse; in this case, we would express Example 15.64 as:

Other places of ciste can be brought out using the grammar of selma'o BAI modals, allowing slightly different forms of expression, thus:

The cmavo le'a , also in selma'o BAI, can be used to specify a category:

which is minimally different in meaning from Example 15.67 .

The cmavo na'e is not the only member of selma'o NAhE. If we want to express a scalar negation which is a polar opposite, we use the cmavo to'e , which is grammatically equivalent to na'e :

Likewise, the midpoint of a scale can be expressed with the cmavo no'e , also grammatically equivalent to na'e . Here are some parallel examples of na'e , no'e , and to'e :

The cmavo to'e has the assigned rafsi -tol- and -to'e- ; the cmavo no'e has the assigned rafsi -nor- and -no'e- . The selbri in Example 15.71 through Example 15.73 could be replaced by the lujvo nalmle , normle , and tolmle respectively.

This large variety of scalar negations is provided because different scales have different properties. Some scales are open-ended in both directions: there is no “ultimately ugly” or “ultimately beautiful” . Other scales, like temperature, are open at one end and closed at the other: there is a minimum temperature (so-called “absolute zero” ) but no maximum temperature. Still other scales are closed at both ends.

Correspondingly, some selbri have no obvious to'e - what is the opposite of a dog? – while others have more than one, and need ci'u to specify which opposite is meant.
