obstetric[obstetric 词源字典]

obstetric: [18] An obstetric nurse is etymologically one who ‘stands before’ a woman giving birth to render assistance. The word is an adaptation of Latin obstetrīcius, a derivative of obstetrīx ‘midwife’. This in turn was formed from obstāre ‘stand in the way’ (source also of English obstacle [14] and oust [16]), a compound verb formed from the prefix ob- ‘before’ and stāre ‘stand’.
