Etymology is simply the true meaning, origin, or history of a word.
What I have here are the true meanings of the names of some major figures from Greek mythology. This can have a lot of interesting uses. If you want to name a pet after a figure from Greek mythology, you can pick a name which truly represents the animal by knowing the etymology behind the name. You can also find out why characters named after figures from Greek myth are named what they're named. For instance, the character Apollo from the Rocky movies fits perfect.
