Helot is a noun that refers to a serf or a servant.
Ancient Greek Region of Helos was known for the subjugation of its people. Soon, our word of the day became a synonym of slave or servant. Here’s an example of it in use:
Chris may be known for treating his assistant like a helot, but I will say this for him: his assistant Jimmy may not have had much freedom, but he was a lot better paid than most.
