Anyway when even babyname sites are calling it a 'culturally loaded choice' maybe your pun isn't worth it?
and if you want to get really deep, there's the fact that the un-inflected form 'adon' derives from the word 'ad', meaning 'father'
and 'ad' just happens to coincidentally mean 'child' in mando'a. Which, usually i'm not going to complain about the etymology of a word conflicting with a completely different language but considering it's already established as a pun, and mando'a is highly agglutinative makes me extremely tempted to interpret it as meaning 'child-____'
okay now that i've explained one way that this is weird i feel like i have to explain the rest in the interests of fairness
there's the fact that it's a pun which, i'm not saying isn't a thing in star wars but is a bit weird
there's the fact that its kinda vaguely blasphemous
there's the fact that duke kryze and his daughter, duchess kryze are the *only* people who use the title of duke/duchess on mandalore, and its really weird that they do because they're an unwieldy fit for Mandalore's clan system
