the action of stopping a fire burning

We need automatic fire fighting installations capable of achieving total control and extinguishment. 我们需要能够实现全面控制和灭火的自动消防设施。

the action of stopping or ending something

Is death any more than the simple extinguishment of life? 死亡仅仅是生命的中止吗？

the fact of destroying or removing a right, a contract, or a debt (= money that is owed to someone else) so that it no longer exists in law

The legal consequence was the extinguishment of the debt. 法律上的后果是债务失效。

If rights over the land are proven, their extinguishment can be the subject of a deal. 如果对土地的权利得到证实，废除所有权可以成为交易的议题。
