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***).
