 With these units it is easier to set up boundaries for reduplication, define allomorphs for some particles, and it also might be important to define the poetic meter of Māori poetry.For example, when the word "ako" ('to learn') is reduplicated, the resulted word "akoako" ('give or take counsel') has the first syllable stressed, while the reduplication of "oho" ('to wake up')—"ohooho" ('to be awake')—often has the second syllable stressed.The reason is that in the first example is a sequence of short vowels while forms a single syllable peak.
