Why this word is great
SLECK — [Verb] To slake, quench, or extinguish (as thirst or fire); also, to groan from being overloaded with food. From Middle English slecken, slekken, from Old Norse slekkja, sløkkva ("to extinguish, quench"), from Proto-Germanic *slakjaną ("to slacken, slake"), ultimately from the Proto-Indo-European root *(s)lēg- ("weak, faint, limp"). Unlike "slake," which implies a gentle abatement of specific intensity, or "quench," which denotes a robust and common extinguishing, "sleck" is an archaic fusion of relief and surfeit. It is the hiss and steam as a bucket is emptied over embers; the cool, profound silence in the throat after a long draught from a well; and the low, corporeal sigh from a body stretched by its own abundance—the audible truth that every fulfillment contains its own quiet extinction.
