Feel former lover returned passion charging a little money (10)
I believe the answer is:
experience
'feel' is the definition.
(synonyms)
'former lover returned passion charging a little money' is the wordplay.
I cannot quite see how this works, but
'former' could be 'ex' (prefix meaning former or onetime) and 'ex' is located in the answer.
'a' could be 'per' (eg 'one a day' means 'one per day') and 'per' is located in the answer.
'money' could be 'c' and 'c' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for experience that I've seen before include "Try" , "Participate in - knowledge and understanding gained" , "Live through; feel" , "Undergo" , "Witness" .)
