A cloak is a long, loose outer garment that hangs from the shoulders, often reaching well down the body. A cape is generally shorter, hanging from the shoulders and covering mainly the back and arms, as in the classic superhero image. Length is the main clue: floor-sweeping usually means cloak, shoulder-to-waist usually means cape.
The core difference
A cloak is typically long and full-length from the shoulders, while a cape is shorter, covering the back and arms.
- cloak — a long, loose outer garment that hangs from the shoulders, often without sleeves: she wrapped her cloak tightly against the cold night air.
- cape — a sleeveless outer garment that hangs from the shoulders and covers the back and arms: Superman's red cape billowed behind him as he flew.
How to tell them apart
Both garments hang from the shoulders, so length is the practical way to separate them: a cloak is the longer, fuller garment, often reaching well down the body, while a cape is the shorter one, often stopping around waist or hip level.
Both words also carry figurative senses. Cloak can mean something that hides the truth, as in a scandal cloaked in secrecy, while cape has a completely separate geographic sense: a headland of land jutting into the sea, as in a ship rounding a cape.
