x_{1} (li) is an x_{3}rd root of x_{2}, with other (identifying) characteristics x_{4}.

This word is related to seltenfa in basically the same way that dugri is related to se'ai'e zei tenfa. Notice that each of fenfa, tenfa, and dugri each can essentially be expressed by permuting the terbri of any one of them. Thus, this word fixes an asymmetry in the definitions. Since there can be many nth roots of a radicand, x_{4} allows for a means of uniquely describing/identifying which one of these options x_{1} is. See also: fe'a.

_{1}abstractly pertains to an exponential/root/logarithmic relationship between the elements of x_{2}(ordered pair) which are related via concrete relationship x_{3}.
