Crossword Genius

Flattering song mouthed to dancing (6-7)

Ross

I believe the answer is:

smooth-tongued

'flattering' is the definition.
(thesaurus)

'song mouthed to dancing' is the wordplay.
'dancing' is an anagram indicator.
'song'+'mouthed'+'to'='songmouthedto'
'songmouthedto' anagrammed gives 'SMOOTH-TONGUED'.
