Corrupt Terry Mulligan (5)
I believe the answer is:
retry
'mulligan' is the definition.
The answer and definition are not the same part of speech.
'corrupt terry' is the wordplay.
'corrupt' indicates anagramming the letters.
'terry' is an anagram of 'RETRY'.
Can you help me to learn more?
(Other definitions for retry that I've seen before include "Hear (a case) again" , "Advice following failure, initially" , "Have another go" , "take second opinion on case" , "Make a further attempt" .)
