Other comments: Yakan has a decimal system, but the numbers eleven to nineteen, twenty one to twenty nine etc. should be different. There are morphophonemic changes. I assume that they are results of assimilation and that the numbers are

thought of as "sɛmpuːʔ duk (and) dɛmbuaʔ" The contracted form becomes "sɛmpukdembua'" the long 'u' is shortened and instead of the glottal there is a 'k'.

The same holds true for all digits like 11 - 19, 21 - 29 etc.
