Maremma

Etymology
Several etymologies have been proposed. The most common is that the area was supposedly known in Roman times as  (meaning “sea-side country”), and that the name came down directly from this Latin designation. Another theory has that the name derives from, meaning “swamp”. This Spanish term also derives from. The area was known for being a malarial swamp (see the article Grosseto in the online Brittanica), and it belonged to the, which was under Spanish control from 1557 to 1707, so a voyage from to  to Maremma does not at all look impossible. Finally, an amateur etymology derives it as + ; the semantic distance remains unexplained.
