Go off to find another partner (6)
I believe the answer is:
repair
'go off' is the definition.
'repair' can be an answer for 'go' (I've seen this before). I am not sure about the 'off' bit.
'another partner' is the wordplay.
'another' becomes 're' (I've seen this in other clues).
'partner' becomes 'pair' (both can mean to form a pairing).
're'+'pair'='REPAIR'
'to find' is the link.
Can you help me to learn more?
(Other definitions for repair that I've seen before include "Proceed - restore" , "Restore, set right" , "Fix, mend" , "retire" , "Correct" .)
