Punisher with rage concealing empty violence (7)
I believe the answer is:
avenger
'punisher' is the definition.
Both the answer and definition are singular nouns.
Perhaps there's an association between them I don't understand?
'rage concealing empty violence' is the wordplay.
'rage' becomes 'anger' (I've seen this in another clue).
'concealing' is an insertion indicator.
'empty' says to hollow out the word (remove centre letters).
'violence' with its middle removed is 've'.
'anger' placed around 've' is 'AVENGER'.
'with' acts as a link.
Can you help me to learn more?
(Other definitions for avenger that I've seen before include "person wanting justice through violence?" , "Fury results" , ""Nemesis"" , "party retaliating" , "Someone seeking to settle a score" .)
