Septentrional, meaning "of the north", is a word that is rarely used in English but is commonly used in Latin and in the Romance languages. Early maps of North America, mostly those before 1700, often refer to the northern- or northwestern-most unexplored areas of the continent at "Septentrional"or "America Septentrionalis", sometimes with slightly varying spellings.
