1. Using "Tatanka" (friend) and "Waun" (welcome):
* Tatanka waun: This literally translates to "Friend welcome" and is a simple way to express it.
* Waun, tatanka: This puts "Welcome" first, making it a bit more formal.
2. Using a more general greeting with a friendly tone:
* Hau! (or Hau kola!) This is the general greeting and is often used in a friendly way. You could add "Tatanka" after it to make it more explicit.
* Hau, tatanka!
* Hau kola, tatanka!
3. A more formal greeting with a welcoming sentiment:
* Wacipi, tatanka! This literally means "Celebration, friend!" and expresses joy and welcome.
* Yuwipi, tatanka! This means "Good, friend!" and expresses a positive welcome.
It's important to note that the best way to express "Welcome, friend" in Lakota depends on the context and your relationship with the person you are greeting.
