Loudly fierce or abusive woman (6)
I believe the answer is:
virago
'loudly fierce or abusive woman' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for virago that I've seen before include "A tough abusive woman" , "Scold" , "Shrew, harpy" , "Strong and aggressive woman" , "Amazon" .)
