Talk with woman custodian of castle (10)
I believe the answer is:
chatelaine
'custodian of castle' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'talk with woman' is the wordplay.
'talk' becomes 'chat' (chat can mean to talk).
'with' says to put letters next to each other.
'woman' becomes 'elaine' ().
'chat'+'elaine'='CHATELAINE'
Can you help me to learn more?
(Other definitions for chatelaine that I've seen before include "Castle keeper" , "As keyholder" , "French mistress" , "Woman running a household" , "Lady of the house" .)
