Squirrels away holy man with remains (7)
I believe the answer is:
stashes
'squirrels away' is the definition.
(I've seen this in another clue)
'holy man with remains' is the wordplay.
'holy man' becomes 'st' (abbreviation for saint).
'with' says to put letters next to each other.
'remains' becomes 'ashes' (I've seen this before).
'st'+'ashes'='STASHES'
(Other definitions for stashes that I've seen before include "Hidden supplies or stores" , "Secret stores" .)
