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).
"of or belonging to the people," especially "pertaining to the common people, popular, vulgar," 1822, from Latinized form of Greek dēmotikos "of or for the common people, in common use," from dēmos "common people," originally "district," from PIE *da-mo- "division," from root *da- "to divide." Originally in English it was used in reference to the simpler of two forms of ancient Egyptian writing (opposed to hieratic or hieroglyphic); the broader sense is by 1831. Used of the popular form of modern Greek since 1927.
