Next is the Hi-Group.  They take the following forms:

            Æ        E       sË       wË       Ö/U      I
   --------------------------------------------------------
   akhi- | akhi-   akhiy-   akhiy-   akhiy-   akhiy-   akh-
   ethi- | ethi-   ethiy-   ethiy-   ethiy-   ethiy-   eth-
   ökhi- | ökhi-   ökhiy-   ökhiy-   ökhiy-   ökhiy-   ökh-

We can note the following patterns:

   * All the prefixes end in -hi- in the Æ-Stem forms.

   * All the prefixes end in -h- in the I-Stem forms.

   * All the prefixes end in -hiy- in all the rest of the forms.

For example:

   akhiæya'tahkwa'  ::  we (excl) tease her
                          we (excl) tease them
   ethiæya'tahkwa'  ::  we (incl) tease her
                          we (incl) tease them
   ökhiæya'tahkwa'  ::  she teases us
                          they tease us
