Here, from Indianz and Native Sun News. A quote:
In the foothills of the sacred Black Hills, the Lakota/Dakota/Nakota language was not only examined and researched in an academic manner, but it was celebrated by the participants of the 6th Annual Tusweca Tiyospaye Language Summit.
Held at the Ramkota Hotel, the language summit drew people from across Indian Country to look at the history, the practical application and the preservation efforts of the language that binds the tribes of the Oceti Sakowin together.
The keynote speaker for the opening ceremonies was recording artist Keith Secola, Anishinabe who spoke about the need to not only preserve the language but to flourish the language through education and application beginning in childhood.
