Can't believe that she knows what skorbut or scurvy is, since the incidence of it in the modern times is really low. I wonder what her IQ is . Lol
I'm not from UK, but in my country we don't really call it scurvy. We just call it vit c deficiency or just low in vitamins. It usually happens in poorer areas here, but it's not that common here. You're from Uk? Well that explains why you know about it, because scurvy became infamous from the tales of british sailors in the past. Maybe Park Hajeong learned it during her exchange student trip in England. I guess thanks for making me realized it.
she could have learnt it from movies or books, many pirate movies/books mangas have mentions of it, also the language on the world/country cloe* is from might have bases on what we know as german, so she would have understood the term.
the term itself is pretty similar to the english word imo.
*with cloe i mean the character cloe, not the current cloe.
