also doggone, colloquial minced epithet, by 1849, Western American English, a "fantastic perversion of god-damned" [Weekley]. But Mencken favors the theory that it is "a blend form of dog on it; in fact it is still often used with it following. It is thus a brother to the old English phrase, 'a pox upon it,' but is considerably more decorous." Dog on it was the usual early spelling, so it was perhaps at least felt as such by those using it.
But there are many examples of similar words serving as euphemistic perversions of God: Compare dod for "God" in many oaths (late 17c. through 19c.); dodgasted (probably "God-blasted," in use late 19c., early 20c.); dod-rot (1842).
masc. proper name; third of the prophets in the Old Testament; via Latin and Greek, from Hebrew Amos, literally "borne (by God)."
1837, American English, from Spanish adios, from phrase a dios vos acomiendo "I commend you to God;" the French form is adieu (q.v.).
Roman god of the underworld, early 14c., from Latin Pluto, Pluton, from Greek Ploutōn "god of wealth," from ploutos "wealth, riches," probably originally "overflowing," from PIE root *pleu- "to flow." The alternative Greek name or epithet of Hades in his function as the god of wealth (precious metals and gems, coming from beneath the earth, form part of his realm). The planet (since downgraded) was discovered 1930 by U.S. astronomer Clyde W. Tombaugh; Minerva also was suggested as a name for it. The cartoon dog first appeared in Walt Disney's "Moose Hunt," released April 1931.
early 12c., from Late Latin Te Deum laudamus "Thee God we praise," first words of the ancient Latin hymn.
late classical god of joy and festive mirth, 1630s, from Latin, from Greek komos "a revel, merrymaking, a band of revelers" (see comedy).
surname, also Osborne, Osbourn, Osbourne, etc., a Scandinavian name (Old Norse Asbiorn, Old Danish Asbiorn) meaning literally "god-bear," from os "a god" (see Oscar) + the Germanic word for "bear" (see bear (n.)). The name is found in England before the Conquest, perhaps directly from Scandinavia; it also was common in Normandy and was brought over from thence.
early 15c., of action, "voluntary;" of persons, "taken in preference to others," especially "chosen by God for some special purpose," from Latin electus, past participle of eligere "to pick out, choose," from ex "out" (see ex-) + -ligere, combining form of legere "to choose," from PIE root *leg- (1) "to collect, gather." The noun meaning "those chosen by God" is from early 15c.
evil spirit, prince of demons, from Latin Asmodaeus, from Greek Asmodaios, from Talmudic Hebrew Ashmeday, from Avestan Aeshma-dæva, "Aeshma the deceitful," from aeshma "anger" (from PIE *eismo-, suffixed form of root *eis- (1), found in words denoting passion; see ire) + daeva- "spirit, demon" (from PIE *deiwos "god," from root *dyeu- "to shine," in derivatives "sky, heaven, god").
1670s, "belief in a deity or deities," (as opposed to atheism); by 1711 as "belief in one god" (as opposed to polytheism); by 1714 as "belief in the existence of God as creator and ruler of the universe" (as opposed to deism), the usual modern sense; see theist + -ism.
Theism assumes a living relation of God to his creatures, but does not define it. It differs from deism in that the latter is negative and involves a denial of revelation, while the former is affirmative, and underlies Christianity. One may be a theist and not be a Christian, but he cannot be a Christian and not be a theist. [Century Dictionary]
