Again the couple hesitate to the Mr Fixit (8)
I believe the answer is:
repairer
'the mr fixit' is the definition.
I can't tell whether this defines the answer.
'again the couple hesitate' is the wordplay.
'again' becomes 're' (prefix meaning 'again').
'the couple' becomes 'pair' ('pair' can be a synonym of 'couple').
'hesitate' becomes 'er' (expression used when hesitating).
're'+'pair'+'er'='REPAIRER'
'to' acts as a link.
Can you help me to learn more?
(Other definitions for repairer that I've seen before include "One who makes good damage" , "One who mends/fixes" , "Mender, restorer" , "One having recourse" , "One who mends" .)
