Empty words to turn to during shock? (3,3)
I believe the answer is:
hot air
'empty words' is the definition.
(synonyms)
'turn to during shock?' is the wordplay.
'turn' says the letters should be written backwards.
'during' is an insertion indicator.
'shock?' becomes 'hair' (shock can mean a mass of hair).
'to' back-to-front is 'ot'.
'ot' put inside 'hair' is 'HOT-AIR'.
'to' is the link.
(Other definitions for hot air that I've seen before include "Loud and empty talk to lift a balloon?" , "Boastful talk or balloon filling" , "Boastful talk or balloon filler" , "Bull" , "Empty boastful talk; balloon lift provider" .)
