Put in a crypt (6)
I believe the answer is:
entomb
'put in a crypt' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for entomb that I've seen before include "Bury in vault" , "Put in a grave" , "put six feet under . . ." , "put to rest" , "Lay to rest in an underground vault" .)
