Pronunciation note: The almost universal pronunciation of sacrilegious as/ˌsækrəˈlɪdʒəs/Show Spelled Pronunciation[sak-ruh-lij-uhs]Show IPAis the result of folk etymology—modifying the pronunciation of an unfamiliar word so that it conforms to a more familiar one—in this case religious. Etymologically, sacrilegious has no direct relationship to religious. The historical pronunciation/ˌsækrəˈlidʒəs/[sak-ruh-lee-juhs]occurs in American English, though not in British English, and criticism of the newer pronunciation has almost disappeared.
