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' (both can mean an attempt).
'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" .)
