Like some cows or vows (6)
I believe the answer is:
sacred
'like some cows or vows' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for sacred that I've seen before include "Religious" , "'Hallowed, holy (6)'" , "devoted to deity" , "Like gravestones maybe" , "Hallowed, consecrated" .)
