We heard very little (3)
I believe the answer is:
wee
'very little' is the definition.
(I've seen this in another clue)
'we heard' is the wordplay.
'heard' becomes 'e' (I've seen this in other clues).
'we'+'e'='WEE'
(Other definitions for wee that I've seen before include "Jimmy" , "Minute" , "Slash" , "Mini in Glasgow?" , "Little (Scottish)" .)
