Weep about Herald discarding 50% of fruit (6)
I believe the answer is:
cherry
'fruit' is the definition.
(I know that cherry is a type of fruit)
'weep about herald discarding' is the wordplay.
'weep' becomes 'cry' (synonyms).
'about' indicates putting letters inside.
'herald discarding' becomes 'her' (I can't explain this - if you can you should believe this answer much more).
'cry' going around 'her' is 'CHERRY'.
'50% of' is the link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for cherry that I've seen before include "Bright red" , "Virginity (slang)" , "Greyfriars Bob" , "one likely to be picked?" , "'Tree, fruit and colour (6)'" .)
