"full of reproach, intended to bring disgrace" (of language, words, etc.), late 14c., from Old French oprobrieus (Modern French opprobrieux) and directly from Late Latin opprobriosus, from Latin opprobare "to reproach, taunt," from assimilated form of ob "in front of, before" (see ob-) + probrum "reproach, infamy," from Proto-Italic *profro-, from PIE *probhro- "what is brought up" (against someone, as a reproach), from root *bher- (1) "to carry," also "to bear children." Compare Sanskrit prabhar-, Avestan frabar- "to bring, offer." The etymological sense is "disgrace attached to conduct considered shameful." Related: Opprobriously; opprobriousness.
