panoply n.

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).

"heavy-armed foot soldier of ancient Greece," 1727, from Greek hoplites "heavy-armed," as a noun, "heavy-armed soldier, man-at-arms," from hopla "arms and armor, gear for war," plural of hoplon "tool, weapon, implement." One who carries a large shield, as opposed to a peltastes, so called for his small, light shield (pelte).
