14. Why do soldiers fight?One answer is hidden away in the word soldier itself. Its first recorded occurrence is found in a work composed around 1300, the word having come into Middle English (as soudier ) from Old French soudoior and Anglo-Norman soudeour. The Old French word, first recorded in the 12th century, is derived from sol or soud, Old French forms of Modern French sou. There is no longer a French coin named sou, but the meaning of the word sou alerts us to the fact that money is involved. Indeed, Old French sol referred to a coin and also meant “pay,” and a soudoior was a man who fought for pay. This was a concept worth expressing in an era when many men were not paid for fighting but did it in service to a feudal superior. Thus soldier is parallel to the word mercenary, which goes back to Latin merc?nn3rius, derived from merces, “pay,” and meaning “working for pay.” The word could also be used as a noun, one of whose senses was “a soldier of fortune.”
士兵们为什么而打仗?其中一个答案就隐藏在soldier 这个单词里面。 在大约1300年的一本著作中发现了这个词的最早记载。这个词由古法语的soudoior 和盎格鲁诺曼底语中的 soudeour 进入中古英语（形式为 soudier )。 古法语中的这个单词，最早记录于12世纪，是由sol 或 soud ，现代法语单词 sou 的古法语形式衍变而来的。 已经没有叫做sou 的法国硬币了， 但是单词sou 的意思使我们意识到这和钱有关。 实际上，古法语中的sol 指的是一枚硬币， 也意味着“报酬”，而soudoior 是一个为了报酬而打仗的人。 在许多人打仗并没有得到报酬而是给封建王服役的时代里，这种概念是值得表达出来的。这样，士兵(soldier) 类似于 雇佣兵(mercenary) ， 可以追溯到拉丁文mercennarius ， 由merces “报酬”衍变而来， 意思是“为报酬而工作”。这个词也能当名词使用，其中的一个意思是“雇佣兵”
