countermeasures の語源・成り立ち Etymology
接頭辞counter-はラテン語contrā（反対に）、語根measureはmēnsūra（測定・手段）に由来します。「反対への措置」という字義そのままに、脅威に対する対抗手段＝「対策」を直感的に表します。同じ構造の関連語にcounterattack（反撃）があります。
Countermeasures is the regular plural of countermeasure. The prefix counter- came through French and ultimately reflects Latin contra, “against” or “opposite.” Measure entered English through Old French from Latin mensura, referring to measurement and later to an action or means adopted for a purpose. Their combination literally denotes a measure taken against something, which developed into the modern sense of a response to a danger, attack, or problem.
