Place in a crypt (6)
I believe the answer is:
entomb
'place 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 "Place in a sepulchre" , "put in ground" , "Bury in vault" , "shut up patients?" , "cover late arrival" .)
