midwife 助产士，接生婆

mid-,伴随，相伴，wife,女人。用于指古代的接生婆，现在的助产士。

midwife: midwife: [14] A midwife is etymologically a ‘with-woman’. The mid- element represents the long extinct preposition mid ‘with’ (its Germanic relatives are still alive and well: German mit, Dutch met, and Swedish and Danish med). Wife preserves the original meaning of Old English wīf, ‘woman’. The idea underlying the word is that a midwife is ‘with’ a woman giving birth.
midwife (n.): c. 1300, "woman assisting," literally "woman who is 'with' " (the mother at birth), from Middle English mid "with" (see mid) + wif "woman" (see wife). Cognate with German Beifrau.

2. "You're doing really well," her midwife said encouragingly.: “你做得很好，”助产士鼓励道。

5. Tell your midwife what you want so she can make a note of it and avoid misunderstandings.: 把你的要求告诉助产士，这样她可以记下来，避免产生误解。
