One after crab and lion catching a shrew (6)
I believe the answer is:
virago
'shrew' is the definition.
(virago is a kind of shrew)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for virago that I've seen before include "noisy woman" , "Strong and aggressive woman" , "Dominating woman" , "domineering female" , "Bad-tempered woman" .)
