to sell the pass成为叛国者

【使用地区】：爱尔兰

【释义】：

To be a traitor．Irish legend holds that when a regiment of Crotha，Lord of Atha，was holding a pass against the invading army of Trathal，the“King of Cael，”one of Crotha’s soldiers betrayed the pass for money，the invaders were victorious，and Trathal became King of Ireland．This inspired the ancient Irish expression selling the pass，“betraying one’s own for money or other gain．”

意为“成为叛国者”。爱尔兰传说中，Atha勋爵担任Crotha兵团首领，保卫关隘，抵御高卢国王Trathal军队的入侵。Crotha兵团的一个士兵为了金钱将关隘出卖。这引发了古老的爱尔兰表达方式“出卖关隘”，意为“为了金钱或其他利益出卖自己的一方。”
