She's catty in a big way (7)
I believe the answer is:
tigress
This could be a double definition.
'she's' is the first definition.
Both the answer and definition are singular nouns.
Perhaps there's an association between them I don't understand?
'catty in a big way' is the second definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
Can you help me to learn more?
(Other definitions for tigress that I've seen before include "Striped female animal" , "Wild woman" , "Ferocious female" , "Wild animal" , "Large she-cat" .)
