英语词汇knuckle down的起源、历史背景-英语词源词典

knuckle down. Marble players may have been responsible for this expression, which dates back to 17th-century England. One rule in the game provides that a player must shoot directly from the spot where his marble lands, which requires that he put his knuckles on the ground, or “knuckle down.” Since mar- bles was a popular pastime with adults as well as children at the time, knuckle down possibly came to express earnest applica- tion to any job. However, the bones of the spinal column were also known as “knuckles” in the 17th century, and the expres- sion may therefore derive from the act of “putting one’s back into a task.”
