Don't give up in attempt to get a win (3,5)
I believe the answer is:
try again
'don't give up' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.
'attempt to get a win' is the wordplay.
'attempt to' becomes 'try' (I've seen this in other clues).
'get' says to put letters next to each other.
'win' becomes 'gain' (synonyms).
'try'+'a'+'gain'='TRY AGAIN'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for try again that I've seen before include "Renew endeavour like Robert the Bruce" , "Have another go" .)
