concussive

The word 'concussive' originates from the Latin verb concussus, the past participle of concutere, meaning "to shake violently" or "dash together." This verb itself is a compound of the intensive prefix con- ("together, completely") and quatere ("to shake, strike"). The core semantic logic has remained remarkably consistent: the ancient action of violently shaking or striking together evolved into the modern medical and general sense of relating to a violent shock or impact. The suffix -ive was later appended in English to form the adjective, describing something that has the nature or tendency to cause such a shock.
