housekeeper (n.) Look up housekeeper at Dictionary.com
mid-15c., "householder," from house (n.) + keeper. A later equivalent of householder. The sense of "female head domestic servant of a house" is from c. 1600 (to keep house, as part of a wife's duty, is from late 14c.). Housekeep (v.) is from 1842 and appears to be a back-formation.
