Quadral

These are the three best claims for quadrals. There are several false trails in the literature, that is, suggestions of other Austronesian languages with quadrals, which turn out in fact to have four number values not five.

Likewise, expression of quadral is accomplished in the same way by establishing specific locations or points in signing space.

While the coding of the person distinctions in Tolai is not as transparent as in Tok Pisin, the coding of number shows obvious relations to the number words of this language […] perhaps evidence of a quadral that was generalized to a plural.

Another point is that, judging from the existing descriptions, true trials are extremely rare and true quadrals do not exist.

The number categories of JSL pronouns are singular, dual, trial, quadral and plural.

"A polynomial P(x₁, ..., xₙ is called quadral if it splits into a product of quadratic (or linear) functions in the complex field of coefficients."

If we wished to divide the quadrals into classes, there are obviously several ways in which it could be done, all of them arbitrary. The arbitrariness arises because the points exhibit no natural clustering.

The first instinctive step in revising written matter looks to an effecting of quadrals; any later revision aims at a perfecting of the rhythma.

thanks to the rhythma, in dividing correctly many simple quadrals, in more involved sentences our arrangement shows regularly these simple quadrals expanding into "periods,"

I like to call 4-person interactions and relational systems 'quadrals' (845—846). Their potentially visible occurrence in encounter type groups probably varies widely, and is not often discriminated unless in groups literally composed of couples.

[…] in Konomala, Patpatar, Tolai, Kandas, Duke of York and Siar of New Ireland, these quadral forms have replaced the original plurals.

In some languages, such as Kenyah, a true quadral number also occurs in the pronoun system.

In several cases, plural pronouns clearly derive from historical trial and quadral forms.
