This land could be Mohican, a Dakotan discovered (6)
I believe the answer is:
canada
'this land' is the definition.
(Canada is an example)
'mohican a dakotan discovered' is the wordplay.
'discovered' says the answer is hidden in the clue (remove the letters covering the answer in the clue).
'CANADA' is hidden in the letters of 'mohican a dakotan'.
'could be' acts as a link.
(Other definitions for canada that I've seen before include "part of the world" , "Country to north of USA" , "Maple leaf country" , "Second largest country in the world by area" , "Country with six time zones" .)
