"The word soldier derives from the Middle English word soudeour, from Old French soudeer or soudeour, meaning mercenary, from soudee, meaning shilling's worth or wage, from sou or soud, shilling. The word is also related to the Medieval Latin soldarius, meaning soldier (literally, "one having pay"). These words ultimately derive from the Late Latin word solidus, referring to an Ancient Roman coin used in the Byzantine Empire."

I have some old pre 1789 French sols. It might be the only thing of value I will have left once the CAD crashes...
