Panhellenic adj.

word-forming element meaning "all, every, whole, all-inclusive," from Greek pan-, combining form of pas (neuter pan, masculine and neuter genitive pantos) "all," from PIE *pant- "all" (with derivatives found only in Greek and Tocharian).

Commonly used as a prefix in Greek (before a labial pam-; before a guttural pag-), in modern times often with nationality names, the first example of which seems to have been Panslavism (1846). Also panislamic (1881), pan-American (1889), pan-German (1892), pan-African (1900), pan-European (1901), pan-Arabism (1930).

"pertaining to Greece," 1640s, from Greek Hellēnikos "Hellenic, Greek," from Hellēn "a Greek," a word of unknown origin; traditionally from the name of an eponymous ancestor, Hellēn, son of Deucalion. To Homer the Hellenes were a small tribe in southern Thessaly (his word for one of the Greek-speaking peoples is our Achaean). In modern use in the arts, Hellenic is used of Greek work from the close of the primitive phase to the time of Alexander the Great or the Roman conquest (succeeded by the Hellenistic).
