He goes into a ship and remains (5)
I believe the answer is:
ashes
'remains' is the definition.
(I've seen this before)
'he goes into a ship' is the wordplay.
'goes into' means one lot of letters goes inside another.
'ship' becomes 'SS' (prefix in ship names eg SS Great Britain).
'a'+'ss'='ass'
'he' inserted within 'ass' is 'ASHES'.
'and' acts as a link.
(Other definitions for ashes that I've seen before include "Eng./Aus. cricket trophy" , "''... to ..., dust to dust'' (burial service)" , "Remains of the Yule logs?" , "Remains from a cremation" , "sports contest" .)
