Ben sadly has another chap to bury (6)
I believe the answer is:
entomb
'to bury' is the definition.
(synonyms)
'ben sadly has another chap' is the wordplay.
'sadly' is an anagram indicator.
'has' indicates putting letters inside.
'another chap' becomes 'tom' (a man's name. I am not sure about the 'another' bit.).
'ben' anagrammed gives 'enb'.
'enb' going around 'tom' is 'ENTOMB'.
Can you help me to learn more?
(Other definitions for entomb that I've seen before include "cover late arrival" , "Inter" , "Cover - bury - hide" , "dispose of the dead" , "Bury in vault" .)
