About yak titʸu titʸu yak tiłhini Tribe
The Name
The Tribe ask that the first time it is used, their name is spelled out in its entirety—yak titʸu titʸu yak tiłhini, Northern Chumash Tribe of San Luis Obispo County and Region—and after, the abbreviation ytt Tribe is appropriate to use. The “y” is not capitalized since they don’t have capital letters in tiłhini. Ensure the “T” in Tribe is capitalized (this is good practice for any scenario referencing specific tribes). A “the” should not precede ytt Tribe since “yak” means “the”.
tiłhini is its own language, not a dialect. tiłhini is also the name for their language, as well as the place name for today's San Luis Obispo

Fast Facts
- Tribes are political groups: Tribes are, governments, Tribes are not racial or ethnic groups.
- Working with a Tribe is like working with a foreign government—respect, demonstrating the appropriate authority, and title are important (see first sentence). Just as we wouldn't have a student reach out to the leader of another country's government, we shouldn't have students reaching out to ytt Tribal Leader. It is important that Department chairs and faculty members make the enduring relationships themselves.
- Relationship is key to all Tribal matters.
- Let the Tribe lead: in SLO this means to involve ytt Tribe as partners in the “fun stuff.” They've shared it can feel transactional or possibly exploitive when knowledge exchanges are not grounded in relationship and abruptly end after they share knowledge/perspective. This is a good idea when working with different Tribes throughout your career: ask the Tribes what they want to be engaged in and where they want to lead.
- Validate Indigenous knowledge as legitimate scientific knowledge. Too often people divorce the two.
