Scold for always standing around (7)
I believe the answer is:
reprove
'scold' is the definition.
(thesaurus)
'for always standing around' is the wordplay.
'for' becomes 'pro' (I've seen this before).
'always' becomes 'ever' ('ever' can be a synonym of 'always').
'standing' shows that the letters should be reversed in order.
'around' is an insertion indicator.
'ever' in reverse letter order is 'reve'.
'pro' going within 'reve' is 'REPROVE'.
(Other definitions for reprove that I've seen before include "Criticise" , "Rebuke, censure" , "Chide" , "tick off" , "To remonstrate" .)
