Canadian territory bigger than the UK (5)
I believe the answer is:
yukon
'canadian territory' is the definition.
(one of the territories of Canada)
'bigger than the uk' is the wordplay.
I cannot really understand how this works, but
'uk' is present in the answer.
The remaining letters 'yon' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for yukon that I've seen before include "Canadian territory adjoining Alaska" , "River of northwest US and Canada" , "mineral-rich area" , "Canadian territory, famed for the 1897 gold rush" , "Territory of NW Canada, east of Alaska" .)
