Did you know?
The original chatelaine's domain was a castle or fort, and the chatelaine's duties were many. To complete them, she certainly needed keys. In the 18th century, the word chatelaine (borrowed from the French châtelaine) took on an additional meaning in English that alluded to this: the word came to be used for a decorative clasp or hook from which chains holding a watch, purse, keys, etc. were suspended. These popular accessories evoked the bunch of keys the original chatelaine had worn of necessity.
