Other comments: Langam or Pondi makes use of a quinary numeral system.

    The word for ‘five’ (ipakwaⁿdap) is a compound consisting of ipa ‘hand’ and kwaⁿdap ‘one’ (literally, ‘one hand’), reflecting the system of hand-counting that underlies the quinary numerical system

    The numbers six through nine contain the verbal element matpe, which denotes that a given number has been added (to the number five; the word ipakwaⁿdap is probably elided).

   The number ten is of the form ‘five (times) two’; the number fifteen is of the form ‘five (times) three’; and the number twenty is of the form ‘five (times) four’. It is unknown how numbers larger than twenty-four are formed (if they are ever formed at all).

   Pondi, identified as “Langam” is a moribund language with about 300 population spoken at Langam village in Angoram District, East Sepik Province, Papua New Guinea.
