Go and get married again? (6)
I believe the answer is:
repair
'go' is the definition.
(I've seen this before)
'married again?' is the wordplay.
I cannot really understand how this works, but
'again?' could be 're' (prefix meaning 'again') and 're' is located in the answer.
The remaining letters 'pair' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'and get' acts as a link.
(Other definitions for repair that I've seen before include "Maintain" , "remedy" , "Restore to working condition" , "do some darning" , "Withdraw" .)
