nurse [nurse 词源字典]: nurse: [13] The ultimate source of nurse was Latin nūtrīre (which also gave English nourish [13], nutriment [16], and nutrition [16]). This originally meant ‘suckle’ (it is related to Sanskrit snauti ‘drips, trickles’), but was later generalized to ‘feed, nourish’ and ‘look after’. Both ‘suckle’ and ‘look after’ are preserved in nurse, which comes via Old French nourice from the late Latin derivative nūtrīcia, although originally the ‘looking after’ was restricted to children: the notion of a nurse as a ‘carer for sick people’ did not emerge in English until the end of the 16th century.

The derivative nursery [16] retains its associations with children, and by extension with young plants. Late Latin nūtrītūra ‘feeding’, based on nūtrīre, gave English nurture [14].
