Song from star I applauded (4)
I believe the answer is:
Here is my best explanation:
'song' is the definition.
(aria is a kind of song)
'from star i applauded' is the subsidiary indication.
'from' indicates a hidden word.
'aria' is hidden within 'star i applauded'.
(Other definitions for aria that I've seen before include "A song from an opera", "An operatic song", "Operatic vocal", "Operatic air", "Song for solo voice from an oratorio, cantata etc", "Song such as "Your Tiny Hand is Frozen"", "Type of song", "Imitative art work", "Opera solo" and "Operatic tune".)
