From earlier sesspool. Origin uncertain.
Possibly an alteration of English dialectal suspool, from suss, soss (“puddle; mire”) + pool. Alternatively, from a folk etymology (influence from pool) from earlier cesperalle, alteration of Middle English suspiral, from Middle French souspirail (“air hole”), from soupirer, souspirer (“to sigh, breathe”), from Latin suspirare.
cesspool (plural cesspools)
