'iipaach: "Men", plural of 'iipa or 'iipach, "man" (Tiipay). Here the speaker added nominative suffix -ch, making it 'iipaachech. The shwa (e) inserted before the suffix may not be audible, and the suffix may sound like it part of the next word, especially since the next word begins with a vowel.
uuwich: "They see (it)." This plural form is used in Tiipay, however for the singular form, speaker Rosalie Robertson uses 'Iipay ewuuw "sees, looks at" rather than Tiipay uwiiw.
