slake

Etymology

This word came from Middle English slaken (“to render slack, to slake”), from Old English sleacian, from Old English slæc (“slack”). It is unrelated to, though possibly influenced by, Old Norse sløkkva (“to extinguish”); compare Swedish släcka in the phrases släcka sin törst (“quench one's thirst”) and släcka elden (“put out the fire”), and släckt kalk (“slaked lime”).
