Other comments: Biak has a decimal system, this language is predominantly ( about 70,000 speakers) spoken on the islands Biak, Papua province, Eastern Indonesia. To combine the tens with the simple units of 1 till ten, one uses the word sesr or sesr di. The word sesr can be analyzed as a noun, related to the word eser 'one', and be translated as 'unit'. The word di, on the other hands, is an allophone of the ri that links numerals with the noun that they modify, as we will see and the analysis explains why the word for 'eleven' is samfur sesr eser, without the linker ri, whereas the word for 'twelve' is samfur sesr ri suru. The numeral linker ri is not used to link a noun with the number eser, but only for the linking of a noun with one of the numbers two till nine. The words for 'eleven', twelve', 'twenty four' and 'nine hundred eleven' then can be analyzed as followsː

 11. samfur sesr oser ː 'ten (and) one unit '

 12. samfur sesr di suru ː 'ten (and) NUM.LNK two unit '

 911. utin di siw samfur sesr oser ː 'hundred NUM.LNK nine ten unit one ',
     'nine hundreds ten (and) one unit ' > nine hundred eleven.

10.0000. syaran samfur

1.000.000. juta (loanword from Indonesian)

We can see in attributive position the cardinal numbers up to and including nine - except eser / oser 'one' - are linked to the preceding noun by the numeral linker ri. The numeral eser / oser 'one' can be modify the noun by simple juxtaposition, while the numerals samfur 'ten' can be linked by simple juxtaposition or by the numerals linker ri. Numbers higher than ten can only be linked with the preceding noun by juxtaposition.
