To be honest, left a woman money (5)
I believe the answer is:
level
'to be honest' is the definition.
(level can mean fair or honest)
'left a woman money' is the wordplay.
I cannot really see how this works, but
'left' could be 'l' (common abbreviation) and 'l' is found within the answer.
'woman' could be 'eve' (Eve is an example) and 'eve' is located in the answer.
'money' could be 'l' (L can mean 'pounds') and 'l' is found within the answer.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for level that I've seen before include "Device ot establish a flat surface" , "Palindromic storey" , "Experience an evening out" , "Uniform" , "Palindromically smooth" .)
