High point that turns up in rotation (3)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
tor
'high point' is the definition.
(a tor is a rocky hill)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for tor that I've seen before include "Feature of Dartmoor" , "Rocky prominence" , "(Dartmoor) rocky hill" , "fell" , "Rot on rocky peak" .)
