Did you hear about the extinction of the passenger pigeon?

Root Explanation

Extinction → It is formed from "ex-" (meaning out) and "stinguere" (meaning to quench or extinguish). The word "extinction" refers to the state of being extinguished or wiped out, particularly in the context of species no longer existing.

Memory Tip

Think of something being 'quenched' or 'put out' ('stinguere') completely 'out' ('ex-') — that's why extinction means the complete disappearance of a species.
