'emp remains (3)
I believe the answer is:
ash
I believe this is a double definition.
''emp' is the first definition.
('hash' - thesaurus - said with a cockney accent, dropping the 'H', like 'hemp' was)
'remains' is the second definition.
(remains of a fire)
(Other definitions for ash that I've seen before include "Oleaceous tree" , "Woodland tree; result of burning" , "Tree in danger" , "Tree with silver-grey bark" , "One [TYPE OF TREE]" .)
