Point the finger retaining right to condemn (7)
I believe the answer is:
accurse
'right to condemn' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.
'point the finger retaining' is the wordplay.
'point' becomes 'r' (I can't justify this - if you can you should give a lot more credence to this answer).
'the finger' becomes 'accuse' (I've seen this in another clue).
'retaining' means one lot of letters goes inside another (inserted letters are held or retained).
'r' put inside 'accuse' is 'ACCURSE'.
Can you help me to learn more?
(Another definition for accurse that I've seen is " Damn".)
