Countermeasure
KOWN-ter-mez-her
/ˈkaʊntərmɛʒər/
An action or device designed to prevent an undesirable effect or to counteract a threat.
It implies a reactive or preventative action specifically taken to nullify or reduce the impact of an opposing action or threat.
The story behind the word. The word 'countermeasure' is a straightforward combination of 'counter-' (meaning 'against' or 'opposite') and 'measure' (meaning 'an action' or 'a step'). It emerged in the mid-20th century, particularly in military and technical contexts, to describe an action specifically taken 'against' an existing or anticipated 'measure' (action) by an adversary. It's a practical term for any defensive or preventative step.
Word relationships
- defense: Broader term, can refer to the overall system or strategy, not just a specific action.
- precaution: An action taken in advance to prevent something undesirable, but less about actively nullifying an existing threat.
- threat: The danger or intention to cause harm, which countermeasures are designed to oppose.
- vulnerability: A weakness that countermeasures aim to protect against.
Commonly confused with
