'extinct' originates from Latin, specifically the word 'extinctus,' where 'ex-' meant 'out' and 'stinguere' meant 'to quench or extinguish.'

'extinctus' transformed into the Old French word 'estinct,' and eventually became the modern English word 'extinct' through Middle English.

Initially, it meant 'to quench or put out,' but over time it evolved into its current meaning of 'no longer in existence.'
