We heard very little (3)
I believe the answer is:
'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).
(Other definitions for wee that I've seen before include "Jimmy" , "Minute" , "Slash" , "Mini in Glasgow?" , "Little (Scottish)" .)
