Hoard stone and wood (5)
I believe the answer is:
stash
'hoard' is the definition.
('stash' can be a synonym of 'hoard')
'stone and wood' is the wordplay.
'stone' becomes 'st'.
'and' is a charade indicator (letters next to each other).
'wood' becomes 'ash' (I've seen this before**).
'st'+'ash'='STASH'
(Other definitions for stash that I've seen before include "(Hidden store of) drugs" , "Secret(ly) store" , "Secret store of valuables" , "Consignment of drugs" , "Squirrel away" .)
