Etymology
Origin of extinguish

Explanation
To extinguish something means to put an end to it, and get rid of it completely. Water can extinguish a fire; nasty smells can extinguish your appetite. Extinguish comes from the Latin word for quench, but while we might think that quenching something, say our thirst, is good, the word extinguish often has sinister overtones. In a genocide, one group tries to extinguish another — too quench their hatred, by killing everyone in the other group.
