Again, summarise wild caper (5)
I believe the answer is:
recap
'again summarise' is the definition.
'recap' can be an answer for 'summarise' (recapping is a kind of summarizing). I am not certain of the 'again' bit.
'wild caper' is the wordplay.
'wild' indicates an anagram.
'caper' anagrammed gives 'RECAP'.
Can you help me to learn more?
(Other definitions for recap that I've seen before include "In brief, say it again" , "Sum up what has been said" , "Reiterate" , "Summary of main points" , "Go over again in the mind" .)
