The process of purifying or refining something, especially by removing impurities or unwanted elements.
From French épuration, derived from Latin epuratus (cleaned, purified), combining e- (out) and puratus (made pure) from purus (pure). The term evolved in French to describe the systematic removal of contaminants or undesirable elements.
This word saw a grim resurgence during the Cold War and post-WWII era, when governments used 'épuration' to describe the removal of political enemies and collaborators—showing how neutral-sounding scientific terms can mask darker historical purposes.
