What is the meaning of Greek root name Andromeda?

The Greek root of the name Andromeda is "andros" which means "man" and "meda" which means "ruler".

Therefore, Andromeda literally means "ruler of men".

It's interesting to note that while the name literally means "ruler of men," in Greek mythology, Andromeda was actually a princess who was chained to a rock as a sacrifice to appease the sea monster Cetus.
