Place in a sepulchre (6)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
entomb
'place in a sepulchre' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for entomb that I've seen before include "Incarcerate" , "cover late arrival" , "dispose of the dead" , "put six feet under . . ." , "Inter" .)
