Achilles (son of Zeus)
In Greek mythology, Achilles, also spelled Achilleus, was the son of Zeus and Lamia, and the main subject of a minor myth. He is not to be confused with the more famous Achilles, the hero of the Trojan War.
Etymology
tablets attest to the personal name Achilles in the forms a-ki-re-u and a-ki-re-we ; the latter being the dative of the former.Achilles' name can be analyzed as a combination of ἄχος "distress, pain, sorrow, grief" and λαός "people, soldiers, nation", resulting in a proto-form *Akhí-lāu̯os "he who has the people distressed" or "he whose people have distress". Furthermore, laós has been construed by Gregory Nagy, following Leonard Palmer, to mean "a corps of soldiers", a muster.
Some researchers deem the name a loan word, possibly from a Pre-Greek language. Robert S. P. Beekes has suggested a Pre-Greek origin of the name, based among other things on the coexistence of -λλ- and -λ- in epic language, which may account for a palatalized phoneme /ly/ in the original language.
