Store remains on street (5)
I believe the answer is:
stash
'store' is the definition.
(I know that stash is a type of store)
'remains on street' is the wordplay.
'remains' becomes 'ash' (remains of a fire).
'on' is a charade indicator (letters next to each other).
'street' becomes 'st' (abbreviation).
'ash' put after 'st' is 'STASH'.
(Other definitions for stash that I've seen before include "Squirrel away" , "Secret store (colloq.)" , "Hide in a secret place" , "Consignment of drugs" , "(Illegal) hoard" .)
