Actors Kingsley and Courtenay, maybe, cycled to Bury (6)
I believe the answer is:
entomb
'bury' is the definition.
(I know that bury can be written as entomb)
'actors kingsley and courtenay maybe cycled to' is the wordplay.
I cannot really understand how this works, but
'and' could be 'n' (common abbreviation for 'and') and 'n' is found within the answer.
'to' is within the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for entomb that I've seen before include "to finish Aida, for example" , "Incarcerate" , "Place in a grave" , "Lay to rest in an underground vault" , "dispose of the dead" .)
