Ghosti > Breaking The Druids Bread

This odd looking word, *ghos-ti, is the Proto-Indo-European word which refers to the reciprocal relationships of hospitality.

 In fact, the English words "guest" and "host" both come from this root (the * at the beginning of the word just means that it's a word reconstructed by linguists and not attested in literature or archeology). 

Our religion in ADF is based on this idea, that we can form relationships with the Powers by making offerings to Them, with the expectation that we may receive blessings and wisdom from Them in return. Well, we've invented a new use for it!

(From something at AFD web site but did not save reference link. Term is a bit rare today (At least in my readings). Would love new links on it.TDK)

Guest

guest (n.) 

Old English gæst, giest (Anglian gest) "guest; enemy; stranger," the common notion being "stranger," from Proto-Germanic *gastiz (cognates: Old Frisian jest, Dutch gast, German Gast, Gothic gasts "guest," originally "stranger"), from PIE root *ghos-ti- "stranger, guest; host" (cognates: Latin hostis "enemy," hospes "host" -- from *hosti-potis "host, guest," originally "lord of strangers" -- Greek xenos "guest, host, stranger;" Old Church Slavonic gosti "guest, friend," gospodi "lord, master"); the root sense, according to Watkins, probably is "someone with whom one has reciprocal duties of hospitality," representing "a mutual exchange relationship highly important to ancient Indo-European society." But as strangers are potential enemies as well as guests, the word has a forked path. 

Spelling evolution influenced by Old Norse cognate gestr (the usual sound changes from the Old English word would have yielded Modern English *yest). Phrase be my guest in the sense of "go right ahead" first recorded 1955.

host (n.1) 

"person who receives guests," late 13c., from Old French hoste "guest, host, hostess, landlord" (12c., Modern French hôte), from Latin hospitem (nominative hospes) "guest, host," literally "lord of strangers," from PIE *ghostis- "stranger" (cognates: Old Church Slavonic gosti "guest, friend," gospodi "lord, master;" see guest). The biological sense of "animal or plant having a parasite" is from 1857.
