- concussion
[concussion 词源字典] - 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’.

Hopping Stilts Are the New French Playthings. ... For France and especially Paris has taken to the "pogo" stick, a stick equipped with two rests for the feet. Inside of the stick is a strong spring so that the "pogoer" may take a series of jumps without straining his powers. The doctors claim that the jarring produced by the successive jumps do not serve to injure the spine, as one might at first suppose. This jumping habit is spreading through France and England and the eastern part of the United States. ["Illustrated World," Sept., 1921]
