obstetric (adj.)youdaoicibaDictYouDict[obstetric 词源字典]
1742, from Modern Latin obstetricus "pertaining to a midwife," from obstetrix (genitive obstetricis) "midwife," literally "one who stands opposite (the woman giving birth)," from obstare "stand opposite to" (see obstacle). The true adjective would be obstetricic, "but only pedantry would take exception to obstetric at this stage of its career." [Fowler]. Related: Obstetrical.[obstetric etymology, obstetric origin, 英语词源]
