Catty female (7)
I believe the answer is:
tigress
This could be a double definition.
'catty' is the first definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
'female' is the second definition.
(I know that tigress is a type of female)
Can you help me to learn more?
(Other definitions for tigress that I've seen before include "Female wildcat" , "Fierce woman" , "dangerous animal" , "Large she-cat" , "hunting animal" .)
