NURSE (a shortened form of the earlier “nourice,” adapted through the French from Lat. nutrix, nutrire, to nourish), primarily a woman who suckles and takes care of an infant, and more generally one who has the general charge of children; also a person, male or female, who attends to the sick, and particularly one who has been trained professionally for that purpose (see Nursing).
