Lack of transparency — and compassion — when handling bill (7)
I believe the answer is:
opacity
'lack of transparency' is the definition.
(I've seen this before)
'compassion when handling bill' is the wordplay.
I cannot really understand how this works, but
'bill' could be 'ac' (short for account) and 'ac' is found in the answer.
'compassion' could be 'pity' (pity is a kind of compassion) and 'pity' is found in the remaining letters.
A single letter 'o' remains which might be clued in a way I don't understand.
This may be the basis of clue (or it may be nonsense).
'and' acts as a link.
Can you help me to learn more?
(Other definitions for opacity that I've seen before include "Lack of transparency" , "The quality of being impervious to light" , "Not allowing passage through" , "Obscureness" , "incomprehensible" .)
