Mistress of a number of men? (3)
I believe the answer is:
mrs
This could be a double definition.
'mistress of a number' is the first definition.
The answer and definition can be both people as well as being singular nouns.
Maybe there's a link between them I don't understand?
'men?' is the second definition.
(Mr is an example)
'of' is the link.
Can you help me to learn more?
(Other definitions for mrs that I've seen before include "Mistress (abbrev.)" , "Wife" , "In short, a married woman" , "Form of address for married woman" , "Married female" .)
