8. Indefinite numbers

The following cmavo are discussed in this section:

     ro      PA      all
     so'a    PA      almost all
     so'e    PA      most
     so'i    PA      many
     so'o    PA      several
     so'u    PA      a few
     no'o    PA      the typical number of
     da'a    PA      all but (one) of

     piro    PA+PA   the whole of/all of
     piso'a  PA+PA   almost the whole of
     piso'e  PA+PA   most of
     piso'i  PA+PA   much of
     piso'o  PA+PA   a small part of
     piso'u  PA+PA   a tiny part of
     pino'o  PA+PA   the typical portion of

     rau     PA      enough
     du'e    PA      too many
     mo'a    PA      too few

     pirau   PA+PA   enough of
     pidu'e  PA+PA   too much of
     pimo'a  PA+PA   too little of

Not all the cmavo of PA represent numbers in the usual mathematical sense. For example, the cmavo “ro” means “all” or “each”. This number does not have a definite value in the abstract: “li ro” is undefined. But when used to count or quantify something, the parallel between “ro” and “pa” is clearer:

8.1)   mi catlu pa prenu
       I look-at one person

8.2)   mi catlu ro prenu
       I look-at all persons
Example 8.1 might be true, whereas Example 8.2 is almost certainly false.

The cmavo “so'a”, “so'e”, “so'i”, “so'o”, and “so'u” represent a set of indefinite numbers less than “ro”. As you go down an alphabetical list, the magnitude decreases:

8.3)   mi catlu so'a prenu
       I look-at almost-all persons

8.4)   mi catlu so'e prenu
       I look-at most persons

8.5)   mi catlu so'i prenu
       I look-at many persons

8.6)   mi catlu so'o prenu
       I look-at several persons

8.7)   mi catlu so'u prenu
       I look-at a-few persons
The English equivalents are only rough: the cmavo provide space for up to five indefinite numbers between “ro” and “no”, with a built-in ordering. In particular, “so'e” does not mean “most” in the sense of “a majority” or “more than half”.

Each of these numbers, plus “ro”, may be prefixed with “pi” (the decimal point) in order to make a fractional form which represents part of a whole rather than some elements of a totality. “piro” therefore means “the whole of”:

8.8)   mi citka piro lei nanba
       I eat the-whole-of the-mass-of bread
Similarly, “piso'a” means “almost the whole of”; and so on down to “piso'u”, “a tiny part of”. These numbers are particularly appropriate with masses, which are usually measured rather than counted, as Example 8.8 shows.

In addition to these cmavo, there is “no'o”, meaning “the typical value”, and “pino'o”, meaning “the typical portion”: Sometimes “no'o” can be translated “the average value”, but the average in question is not, in general, a mathematical mean, median, or mode; these would be more appropriately represented by operators.

8.9)   mi catlu no'o prenu
       I look-at a-typical-number-of persons

8.10)  mi citka pino'o lei nanba
       I eat a-typical-amount-of the-mass-of bread.

“da'a” is a related cmavo meaning “all but”:

8.11)  mi catlu da'a re prenu
       I look-at all-but two persons

8.12)  mi catlu da'a so'u prenu
       I look-at all-but a-few persons
Example 8.12 is similar in meaning to Example 8.3.

If no number follows “da'a”, then “pa” is assumed; “da'a” by itself means “all but one”, or in ordinal contexts “all but the last”:

8.13)  ro ratcu ka'e citka da'a ratcu
       All rats can eat all-but-one rats.
       All rats can eat all other rats.
(The use of “da'a” means that Example 8.13 does not require that all rats can eat themselves, but does allow it. Each rat has one rat it cannot eat, but that one might be some rat other than itself. Context often dictates that “itself” is, indeed, the “other” rat.)

As mentioned in Section 3, “ma'u” and “ni'u” are also legal numbers, and they mean “some positive number” and “some negative number” respectively.

8.14)  li ci vu'u re du li ma'u
       the-number 3 − 2 = some-positive-number

8.15)  li ci vu'u vo du li ni'u
       the-number 3 − 4 = some-negative-number

8.16)  mi ponse ma'u rupnu
       I possess a-positive-number-of currency-units.
All of the numbers discussed so far are objective, even if indefinite. If there are exactly six superpowers (“rairgugde”, “superlative-states”) in the world, then “ro rairgugde” means the same as “xa rairgugde”. It is often useful, however, to express subjective indefinite values. The cmavo “rau” (enough), “du'e” (too many), and “mo'a” (too few) are then appropriate:
8.17)  mi ponse rau rupnu
       I possess enough currency-units.
Like the “so'a”-series, “rau”, “du'e”, and “mo'a” can be preceded by “pi”; for example, “pirau” means “a sufficient part of.”

Another possibility is that of combining definite and indefinite numbers into a single number. This usage implies that the two kinds of numbers have the same value in the given context:

8.18)  mi viska le rore gerku
       I saw the all-of/two dogs.
       I saw both dogs.

8.19)  mi speni so'ici prenu
       I am-married-to many/three persons.
       I am married to three persons (which is “many” in the circumstances).
Example 8.19 assumes a mostly monogamous culture by stating that three is “many”.
