Traditionally associated with πηγή (pēgḗ, “spring, fountain, fountain fed by a spring”), especially used to denote springs of Ocean, where Perseus killed Medusa, from whose blood Pegasus sprang. Some have dismissed this as folk etymology and suggest a Pre-Greek origin because of the -ασος suffix.
- Greek: Πήγασος (Pigasos)
