Pole at the Highland Games (5)

I believe the answer is:

caber

I'm a little stuck... Click here to teach me more about this clue!

'pole' is the definition.
(I know that caber is a type of pole)

I cannot understand how the remainder of the clue works.

Can you help me to learn more?

(Other definitions for caber that I've seen before include "Something tossed in the Highlands" , "Tree trunk tossed in sport" , "Thrown tree trunk" , "Scots projectile" , "Wooden pole" .)

I've seen this clue in The Globe and Mail and The Irish News.
