Irish rascal spotted pinching a record by Prince (8)
I believe the answer is:
spalpeen
'irish rascal' is the definition.
(I've seen this before)
'spotted pinching a record by prince' is the wordplay.
'spotted' becomes 'seen' (I've seen this before).
'pinching' is an insertion indicator (taking inside).
'a record by prince' becomes 'palp' (I can't explain this - if you can you should give a lot more credence to this answer).
'seen' placed around 'palp' is 'SPALPEEN'.
Can you help me to learn more?
(Other definitions for spalpeen that I've seen before include "Irish rascal" , "boy" .)
