Word Origin and History for obstetrical



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.
