16. How do Mandalorian names work?

Notice how I called Ragner “Ragner Vizsla,” not Paz Ragner. Jango Fett’s son? Boba Fett. Bo-Katan Kryze’s sister? Satine Kryze. With all these examples and others, you think that the last name is the family name in Mandalorian culture.
So, when Din Djarin adopts Grogu, you’d expect his name to be Grogu Djarin, mouthful as that may be. But no, he’s Din Grogu. And we’re like, what the heck? How does that work beside it obviously being easier to say?
