Ride around the Hog's Back, it being high ground (5)
I believe the answer is:
ridge
'being high ground' is the definition.
(I've seen this in another clue)
'ride around the hog's back' is the wordplay.
'around' means one lot of letters goes inside another.
'back' suggests the final letters (the letter at the back).
The last letter of 'hog' is 'g'.
'ride' enclosing 'g' is 'RIDGE'.
'it' acts as a link.
This may not be correct. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for ridge that I've seen before include "shelf" , "drum" , "Line where two upward sloping surfaces meet" , "High ground" , "Hog's-back" .)
