Trouble with muck around candlestick (10)
I believe the answer is:
disconcert
'trouble' is the definition.
(thesaurus)
'muck around candlestick' is the wordplay.
'muck' becomes 'dirt' (I've seen this before).
'around' indicates putting letters inside.
'candlestick' becomes 'sconce' (sconce is a kind of candlestick).
'dirt' enclosing 'sconce' is 'DISCONCERT'.
'with' is the link.
(Other definitions for disconcert that I've seen before include "upset" , "Shake up" , "Throw" , "Dismay" , "Confuse; worry" .)
