Looking at this list, I have found some other awkward names. Alphabet is not the worst ( but not far IMO)
I feel that the names that are too closely related to an earth only concept are not great because it goes against our vision of the universe.
Gavial, panther, griffon... For animals and beasts.
Other terms like " Pyrrich victory", or other that are referring to something of real history/geography.
So alphabet, in starwars, could be OK, but I know the galaxy speak mostly basic, using Aurebesh. So I am confused.
So don't say starwars fans are insane just because they are consistent. 40 years of fandom cannot be ignored in just 4 years.
