satisfy or put an end to something
quench - satisfy
To ‘quench’ is to quell or suppress something, typically by damping, decreasing, or satisfying it. This formal word was once used solely to refer to extinguishing a fire, but has since expanded to include a wide range of things from desires to thirst. Something that cannot be neutralized in this way is described as being ‘unquenchable’.

Much to our frustration, every time we tried to light a fire at the campsite it was quenched by the heavy rain.
