Fair lady not won by blurred card symbol (5,5)
I believe the answer is:
faint heart
'fair lady' is the definition.
I know nothing about this answer so I cannot tell whether this works.
'not won by blurred card symbol' is the wordplay.
I cannot really understand how this works, but
'not' could be 'nt' (synonyms) and 'nt' is located in the answer.
'card' could be 'heart' (the hearts are a playing card suit) and 'heart' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Another definition for faint heart that I've seen is " chicken".)
