Hearing of award, interfere (6)
I believe the answer is:
meddle
'interfere' is the definition.
(meddling is a kind of interfering)
'hearing of award' is the wordplay.
'hearing of' shows a homophone (sound like).
'award' becomes 'medal' (medal is a kind of award).
'medal' is a homophone of 'MEDDLE'.
(Other definitions for meddle that I've seen before include "Interfere in other people's business" , "Interfere in people's affairs" , "Pink Floyd album" , "Interfere in another's business" , "Stick one's oar in" .)
