A fossilized partitive form of kim (in contrast to the modern form kimmõ), from Proto-Finnic *kümmentä. The partitive was originally used in all multiples of ten from 20 to 90, as can still be seen in for example Finnish kaksikymmentä. It was eventually turned into an independent word, comparable to the English teen.
kimdõ
As a standalone term to refer to "ten" kim is used. -kimdõ is used not only in names of tens (20-90) but with other determiners as well, e.g., mitskimdõ (“~ several dozen”).
