Other comments: Roon or Ron has a traditional quinary, vigesimal numeral system before, but they use a decimal system probably influenced by Biak now. A few comments:
For 2, nuru is used with inanimates, suru with animates, and is also the default form
      used when counting. nu- and su- are the dual verbal agreement prefixes for
      inanimates respectively, while -ru is cognate with the numeral for 2 in other
      Austronesian languages.
For 3 and 4, the -i- in my data would seem to be identical to the 3rd person singular
      animate verbal agreement marker, though I have no explanation for why it occurs
      in just these two numerals, and am not ready to say whether these two forms
      should be considered monomorphemic or bimorphemic.
For 3 I also have the alternative form nggokor, which occurs in attributive position. In
      addition, it is also the verb "to count". I do not yet understand the nature of the
      alternation between these two forms of 3.

   Roon is an endangered language spoken by about 1,000 speakers on Roon island, west of Cenderawasih bay, West Papua province, Indonesia.
