Try cone once if moving sweets (13)
I believe the answer is:
confectionery
'sweets' is the definition.
(thesaurus)
'try cone once if moving' is the wordplay.
'moving' indicates anagramming the letters.
'try'+'cone'+'once'+'if'='tryconeonceif'
'tryconeonceif' with letters rearranged gives 'CONFECTIONERY'.
(Other definitions for confectionery that I've seen before include "Certify on cone (anag)" , "Sugary stuff" , "sweet things" , "Sweets, chocolate etc" , "Sweets, chocolates, etc" .)
