Strikes an artist as an afterthought? (4)
I believe the answer is:
raps
'strikes' is the definition.
(I know this)
'an artist as an afterthought?' is the wordplay.
'an artist as' becomes 'ra' (I can't explain this - if you can you should believe this answer much more).
'an afterthought?' becomes 'ps' (as in a PS in a letter).
'ra'+'ps'='RAPS'
Can you help me to learn more?
(Other definitions for raps that I've seen before include "'Knocks, on the door say (4)'" , "Knocks sharply" , "Sprechgesang pop hits" , "Cracks" .)
