Revered area of land divides a US state (6)
I believe the answer is:
sacred
'revered' is the definition.
(similar in meaning)
'area of land divides a us state' is the wordplay.
'area of land' becomes 'acre' (measurement of land).
'divides' is an insertion indicator (inserted letters divide the word).
'a us state' becomes 'sd' (abbreviation for South Dakota).
'acre' put inside 'sd' is 'SACRED'.
(Other definitions for sacred that I've seen before include "Holy, blessed" , "'Consecrated, holy (6)'" , "Hallowed, consecrated" , "Like gravestones maybe" , "Religious" .)
