Yeah so why didn't they look at the context and go oh they meant Dino instead of dragon. It's just a language barrier?
it isnt due to the language lmao its a cultural barrier.
is kaku's fruit giraffe giraffe no mi or ox ox no mi?
the fruit names quite literally represents the genus and which in the case of dinosaurs (when you consider the context behind the term kyoryu) makes absolutely perfect sense as to why oda names them dragon dragon no mi.
