way past ripe (6)
I believe the answer is:
rotten
'way past ripe' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for rotten that I've seen before include "Decayed or detestable" , "Decaying - quite putrid" , "Decaying or morally corrupt" , "Decayed, putrid" , "Suffering from decay" .)
