词根:pon, pound, pos(it) = to put(放置)

  我们知道来自法文的词根pos也表示“放;置”的意思,有的词根字典书籍上把这pos和pon放在一起了,有的则把这二个分开,例如刘毅词典就把他们分开了,我们这里也把这二个词根分开,以便更好的理解他们的区别与联系。

  词根pon来源于拉丁语 ponere 放 ,词根pos(it)是pon的变体,它们属于一对结合力非常强的同源异形根,pon是ponere的不定式词干,pos(it)是ponere的动名词词干,这族同根词不下百个。-posit- / -pound- 分别为 -pos- / -pon-

的变体;它相应的希腊语词根为:-the- 放,例如:thesaurosis 贮积病。

词根词缀:doul-, dulo-, dul-

【来源及含义】Greek: slave, servile, slavish; servitude; serving

【相关描述】A doula supports a woman and her family in achieving the kind of birth that they desire. A doula works in homes, hospitals, and birth centers; and gives, emotional, physical, and informational support. A careprovider, be he/she a midwife, OB/gyn, or family practitioner, will take care of a woman's prenatal care and birth. A doula is supposed to ensure that someone is always available to look after the mother-to-be emotionally. These objectives are facilitated by communication between the laboring woman, her partner, and her clinical care providers.

As a supportive companion (other than a friend or loved one) a doula is professionally trained to provide birth-labor support. She performs no clinical tasks. A doula also refers to lay women who are trained or experienced in providing postpartum care—mother and newborn care, breastfeeding support and advice, cooking, child care, errands, and light cleaning—for the family. To distinguish between the two types of doulas, one may refer to "birth doulas" and "postpartum doulas".
