Terry, for a change, must have another shot (5)
I believe the answer is:
retry
'terry for a change must' is the definition.
I can't tell whether this definition defines the answer.
'another shot' is the wordplay.
'another' becomes 're' (I've seen this in other clues).
'shot' becomes 'try' (I've seen this in another clue).
're'+'try'='RETRY'
'have' is the link.
Can you help me to learn more?
(Other definitions for retry that I've seen before include "Advice following failure, initially" , "Have another go" , "Hear (a case) again" , "Put on trial again" , "Make a further attempt" .)
