Put dial away for approval (7)
I believe the answer is:
plaudit
'for approval' is the definition.
(plaudit is a kind of approval)
'put dial away' is the wordplay.
'away' is an anagram indicator (letters move away from their original places).
'put'+'dial'='putdial'
'putdial' anagrammed gives 'PLAUDIT'.
(Other definitions for plaudit that I've seen before include "Acclaim" , "Praise, accolade" , "Expression of praise or approval" , "Praise, encomium" , "Cheer" .)
