Word Origin & History

ob- 
prefix meaning "toward, against, across, down," also used as an intensive, from L. ob "toward, against, in the way of, about, before," from PIE base *opi- (cf. Oscan op, Gk. opi- "behind," Hittite appizzis "younger," Lith. ap- "about, near," Gk. epi "on, upon").

obstetrics 
1819, from obstetric (adj.), 1742, from Mod.L. obstetricus "pertaining to a midwife," from obstetrix (gen. obstetricis) "midwife," lit. "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]
