4. The words "xenelasia" and "xenelasy" (take your pick)

both score numerous hits in Google. The former is closer to the Greek original, the latter more anglicized. I can discern no difference in meaning. The Wikipedia article could use some editing; it begins as follows:

"Xenelasia (Ancient Greek: ξενηλασία ... ) was the title given to a set of laws in ancient Doric Crete and Lacedæmonia that proscribed (sic) the exclusion of foreigners and any foreign arts and music into their respective commonwealths."

Plato had entirely too much respect for such xenophobia; see Republic or Laws.
