Hill in East Ord (3)
I believe the answer is:
tor
'hill' is the definition.
(I know that tor is a type of hill)
'in east ord' is the wordplay.
'in' says the answer is hidden in the clue.
'TOR' is hidden in the letters of 'east ord'.
(Other definitions for tor that I've seen before include "Pillar of rock" , "It rises" , "Rocky prominence" , "Rot on rocky peak" , "Hill or rocky peak" .)
