Canadian native confused Cuba with Rio (7)
I believe the answer is:
caribou
'canadian native' is the definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
'confused cuba with rio' is the wordplay.
'confused' indicates anagramming the letters.
'with' means one lot of letters go next to another.
'cuba' put after 'rio' is 'riocuba'.
'riocuba' anagrammed gives 'CARIBOU'.
Can you help me to learn more?
(Other definitions for caribou that I've seen before include "North American Arctic deer" , "Ruminant" , "N. American reindeer" , "Wild animal" , "Arctic beast" .)
