Etymology

Origin of sluice

1300–50; Middle English scluse (noun) < Old French escluse < Late Latin exclūsa, a water barrier, noun use of feminine of Latin exclūsus, past participle of exclūdere to exclude

Explanation

Anything that resembles a water slide with a gate is a sluice — a narrow channel that controls water flow. The word originally comes from an old English word meaning a narrow channel that controlled a flow of water, usually to a watermill, and it still has that meaning. A sluice can also mean a splash — often with cold water and usually done with some vigor. Torture victims in movies sometimes have their faces sluiced to bring them round for further questioning.
