Bread reportedly in hidden store (5)
I believe the answer is:
cache
'hidden store' is the definition.
(I've seen this in another clue)
'bread reportedly' is the wordplay.
'bread' becomes 'cash' (I've seen this before).
'reportedly' indicates a 'sounds like' (homophone) clue.
'cash' is a homophone of 'CACHE'.
'in' is the link.
(Other definitions for cache that I've seen before include "Reserve" , "Hiding place for treasure or stores" , "Put away" , "Hiding-place for treasure etc" , "Hidden storage place" .)
