Conscious about maiden showing refined feelings (9)
I believe the answer is:
sentiment
'refined feelings' is the definition.
(sentiment can mean refined or profound feelings)
'conscious about maiden' is the wordplay.
'conscious' becomes 'sentient' (similar in meaning).
'about' indicates putting letters inside.
'maiden' becomes 'm' (cricket abbreviation).
'sentient' going around 'm' is 'SENTIMENT'.
'showing' is the link.
(Other definitions for sentiment that I've seen before include "Emotional thought" , "General feeling" , "Mawkishness" , "Emotional feeling" , "Emotion, self-indulgent or insincere perhaps" .)
