HuguenotyoudaoicibaDictYouDict
1562, from Middle French Huguenot, according to French sources originally political, not religious. The name was applied in 1520s to Genevan partisans opposed to the Duke of Savoy (who joined Geneva to the Swiss Confederation), and it is probably an alteration of Swiss German Eidgenoss "confederate," from Middle High German eitgenoze, from eit "oath" + genoze "comrade" (related to Old English geneat "comrade, companion"). The form of the French word probably altered by association with Hugues Besançon, leader of the Genevan partisans. In France, applied generally to French Protestants because Geneva was a Calvinist center.
infralapsarian (adj.)youdaoicibaDictYouDict
1731, from infra- + Latin lapsus "a fall" (see lapse (n.)) + ending from unitarian, etc. In reference to the Calvinist doctrine that god's election of some to everlasting life was consequent to his decree to allow the Fall of man, and was thus a remedial measure. Contrasted to supralapsarian, in reference to the belief that He always meant to consign most of mankind to eternal fire and that the decision to create some men to be damned was his first decree. There's also a moderate sublapsarian view. Here the decree to elect those who would believe and leave those who do not believe to damnation also comes after the decree to allow the fall, but the decree to provide salvation for man comes immediately after the decree to elect.
