Running repairs put in and returned (13)
I believe the answer is:
uninterrupted
'running' is the definition.
(thesaurus)
'repairs put in and returned' is the wordplay.
'repairs' indicates an anagram (I've seen 'repaired' mean this).
'and' means one lot of letters go next to another.
'put'+'in'='putin'
'putin' after 'returned' is 'returnedputin'.
'returnedputin' with letters rearranged gives 'UNINTERRUPTED'.
(Other definitions for uninterrupted that I've seen before include "Continuous" , "Continual" .)
