Maybe one has gasped about such a lady! (7)
I believe the answer is:
painted
'maybe one' is the definition.
Both the definition and answer are adjectives. Perhaps you can see an association between them that I can't see?
'gasped about such a lady' is the wordplay.
'gasped about' becomes 'pain' (I can't justify this - if you can you should believe this answer much more).
'such a lady' becomes 'ted'.
'pain'+'ted'='PAINTED'
'has' is the link.
Can you help me to learn more?
(Other definitions for painted that I've seen before include "Pan diet (anag) - put on canvas" , "Decorated" , "made up" , "Coated with colour" , "described" .)
