Scold for putting a sign outside (6)
I believe the answer is:
virago
'scold' is the definition.
(virago is a kind of scold)
'putting a sign outside' is the wordplay.
I cannot quite see how this works, but
'a' is found in the answer.
'sign' could be 'virgo' (Virgo is an example) and 'virgo' is located in the leftover letters.
This accounts for all the letters.
This may be the basis of clue (or it may be nonsense).
'for' is the link.
Can you help me to learn more?
(Other definitions for virago that I've seen before include "Scold" , "noisy woman" , "Formidable female" , "Termagant" , "Dominating woman" .)
