Decoration with nothing inside -- something that's blown in the wind (4)
I believe the answer is:
oboe
'that's blown in the wind' is the definition.
(musical instrument, part of the woodwind section)
'decoration with nothing' is the wordplay.
'decoration' becomes 'obe' (Order of the British Empire award).
'with' indicates putting letters inside.
'nothing' becomes 'O' (looks like zero - 0).
'obe' placed around 'o' is 'OBOE'.
'inside something' is the link.
This may not be correct. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for oboe that I've seen before include "Double-reed woodwind" , "Double-reed wind instrument" , "Woodwind instrument of treble pitch" , "Slender double-reed instrument" , "Producer of notes" .)
