Put into warehouse again to repair (7)
I believe the answer is:
restore
'repair' is the definition.
(I know that repair can be written as restore)
'put into warehouse again to' is the wordplay.
'put into' indicates putting letters inside.
'warehouse' becomes 'res' (I can't explain this - if you can you should believe this answer much more).
'again' becomes 're' (prefix meaning 'again').
'res'+'re'='resre'
'resre' going around 'to' is 'RESTORE'.
Can you help me to learn more?
(Other definitions for restore that I've seen before include "Bring back; renovate" , "Make good, reinstate" , "Build up again" , "Bring back to health" , "Renew, repair; give back" .)
