A sleeveless outer garment that hangs from the shoulders, or a large point of land that sticks out into the sea.
The clothing meaning comes from Latin 'cappa', meaning a cloak or hood, through French and Spanish. The landform meaning likely comes from the same root, with the idea of land wearing a 'cloak' that juts into the water.
Superheroes’ capes and Cape Cod share the same word family. To early sailors, a piece of land sticking into the ocean looked like the earth wearing a cape over its shoulders.
