Violently toss holy rug (7)
I believe the answer is:
roughly
'violently' is the definition.
(thesaurus)
'toss holy rug' is the wordplay.
'toss' indicates anagramming the letters.
'holy'+'rug'='holyrug'
'holyrug' with letters rearranged gives 'ROUGHLY'.
(Other definitions for roughly that I've seen before include "Sort of; with violence" , "Approximately, more or less" , "In the neighbourhood of" .)
