defeat 作为名词是既有战胜的意思，又有失败的意思，是这样吗？

虽然好像之前学的defeat的解释是这么说没错啦，但个人觉着还是倾向战败的意思比较多吧。
MW的解释是：
1 : frustration by nullification or by prevention of success *the bill suffered defeat in the Senate*
2 obsolete : DESTRUCTION
3 a : an overthrow especially of an army in battle b : the loss of a contest
Collins的解释是：
Defeat is the experience of being beaten in a battle, game, or contest, or of failing to achieve what you wanted to.
感觉都是倾向战败的意思。希望对你有帮助~
