Demonstrated how to get between two poles (5)
I believe the answer is:
shown
'demonstrated' is the definition.
(I've seen this in another clue)
'how to get between two poles' is the wordplay.
'to get' indicates putting letters inside.
'between two poles' becomes 'sn' (I can't explain this - if you can you should give a lot more credence to this answer).
'how' put within 'sn' is 'SHOWN'.
Can you help me to learn more?
(Other definitions for shown that I've seen before include "Explained" , "Demonstrated" , "Displayed" , "Exhibited" .)
