Holy rug moved about (7)
I believe the answer is:
roughly
'about' is the definition.
(both can mean approximately)
'holy rug moved' is the wordplay.
'moved' indicates an anagram.
'holy'+'rug'='holyrug'
'holyrug' with letters rearranged gives 'ROUGHLY'.
(Other definitions for roughly that I've seen before include "In the neighbourhood of" , "Sort of; with violence" , "Approximately, more or less" .)
