Uneven zeal's undone South American (10)

I believe the answer is:

venezuelan

'south american' is the definition.
(Venezuelan is an example)

'uneven zeal's undone' is the wordplay.
'undone' indicates anagramming the letters.
'uneven'+'zeal'='unevenzeal'
'unevenzeal' anagrammed gives 'VENEZUELAN'.

(Other definitions for venezuelan that I've seen before include "South American" , "From Caracas, perhaps" , "Native to, eg, Caracas" .)

I've seen this clue in The Times.
