How does one parse treigon*? According to the rules of numerical base construction, either of the following could be true:

  • It could be treig* (30) modified with -on* (reciprocator), thus treigon* means "one-thirtieth."
  • Or it could be tre* (3) compounded with gon* (1/10), thus treigon* means "three tenths."

To clarify this situation, the fractional numerical rule is as follows: The suffix -on* shall take precedence over the compounding of an integral numerical base with a numerical base containing -on*. Thus treigon* means "one-thirtieth."

Note that as a correlary to this rule, one can observe that compounds that do not form proper numerical bases without -on* cannot form proper numerical bases with -on*. For example, the base dwipenkwon* is invalid, and cannot be valid, as a representation of "two-fifths," since dw* and penkw* cannot be compounded. The proper way to express fractions such as this is to use the hyphenated adverbial form (dwe-penkwon*).
