Word History: Why do soldiers fight? One answer is hidden 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 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 mercēnnārius, derived from mercēs, "pay," and meaning "working for pay." The word could also be used as a noun, one of whose senses was "a soldier of fortune."
