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.
