Pangaea is interesting, it sounds more like a feminine name to me. It does make me think of the super continent but it does also have some familiar name sounds as other have pointed out (‘Gia’) which could potentially cause some people to assume its spelling at ‘Pangia’ if they were unaware of the super continent or unfamiliar with ‘aea’ spellings, especially since it can also be pronounced like ‘Gaia’
