## Origin

The idiom is possibly derived from the practice of turning a turtle onto its back, a manoeuvre which renders the animal quite helpless. By placing the creature on its shell, one ensures it cannot right itself, a state of total inversion that transferred to the capsizing of ships. The phrase appears in mid-19th-century maritime contexts, though the exact moment the reptile’s misfortune became a nautical standard remains unrecorded. (disputed)
