Unrestrained self-indulgence of corrupt peers (5)
I believe the answer is:
spree
'unrestrained self-indulgence' is the definition.
The definition and answer can be both acts as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'corrupt peers' is the wordplay.
'corrupt' is an anagram indicator (a corrupted spelling of the word).
'peers' anagrammed gives 'SPREE'.
'of' is the link.
Can you help me to learn more?
(Other definitions for spree that I've seen before include "orgy" , "High old time" , "(Shopping) jaunt" , "Revel" , "Spending bout" .)
