Doubt maiden’s yielding (9)
I believe the answer is:
misgiving
'doubt' is the definition.
(I know that misgiving is a type of doubt)
'maiden's yielding' is the wordplay.
'maiden's' becomes 'mis' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'yielding' becomes 'giving' ('give' can be a synonym of 'yield').
'mis'+'giving'='MISGIVING'
Can you help me to learn more?
(Other definitions for misgiving that I've seen before include "Feeling of doubt" , "Qualm, scruple" .)
