There is a pattern to the digit cmavo (except for ``no'', 0) which is worth explaining. The cmavo from 1 to 5 end in the vowels ``a'', ``e'', ``i'', ``o'', ``u'' respectively; and the cmavo from 6 to 9 likewise end in the vowels ``a'', ``e'', ``i'', and ``o'' respectively. None of the digit cmavo begin with the same consonant, to make them easy to tell apart in noisy environments.
