Word Origin
- concussion
- concussion: [15] The etymological notion underlying concussion is of ‘violent shaking’; the modern connotation of a ‘jarring injury to the brain’ did not emerge until the 16th century. The word comes from late Latin concussiō, a noun derived from the past participial stem of concutere ‘shake violently’. This was a compound verb formed from the intensive prefix com- and -cutere, an alteration of quatere ‘shake, strike’ (its variant quassāre was the source of English quash and cashier ‘dismiss’, and probably lies behind cascara [19], etymologically ‘bark broken off the tree’).The verb concuss is 17th-century. The related percussion [16] comes ultimately from Latin percutere ‘strike through’.=> cascara, cashier, percussion, quash, rescue
