Etymology
Etymology Information

'extinctionist' originates from English, formed from the noun 'extinction' (from Latin 'exstinctio') plus the agent suffix '-ist', where 'extinction' comes from Latin 'exstinguere' meaning 'to extinguish' and '-ist' denotes 'one who practices or advocates'.

Historical Evolution

'extinction' changed from Latin 'exstinguere' (earlier components ex- 'out' + stinguere 'to quench') to Medieval/Old French and Middle English forms such as 'extinctiō'/'extinction', and the modern English agent noun 'extinctionist' was created by adding the suffix '-ist' to 'extinction' in modern English.

Meaning Changes

Initially it related to 'to extinguish' or 'to quench' in a literal sense; over time 'extinction' came to mean 'the state of being brought to an end or ceasing to exist', and 'extinctionist' evolved to mean 'one who advocates or is associated with extinction'.
