Change of accent is appropriate (10)
I believe the answer is:
confiscate
'appropriate' is the definition.
(thesaurus)
'change of accent is' is the wordplay.
'change' is an anagram indicator.
'of'+'accent'+'is'='ofaccentis'
'ofaccentis' is an anagram of 'CONFISCATE'.
(Other definitions for confiscate that I've seen before include "Take control of" , "Impound" , "Take away (property)" , "Seize as penalty - facts on ice (anag)" .)
