From Middle English slaken ("to render slack, to slake"), from Old English sleacian, from Old English slæc ("slack"). Unrelated to, but possibly influenced by, the Old Norse sløkkva ("to extinguish"), compare Swedish släcka in the phrase släcka sin törst, släcka elden, and släckt kalk.
Probably connected with Icelandic sleikja, "to lick", and German schlecken.
