Fishy female? (5)
I believe the answer is:
hussy
'fishy female?' is the definition.
The answer and definition can be both people as well as being singular nouns.
Maybe they are linked in a way I don't understand?
This is all the clue.
Can you help me to learn more?
(Other definitions for hussy that I've seen before include "Promiscuous girl" , "tart" , "An impudent or brazen girl" , "Shameless woman" , "Immoral woman" .)
