Ross

I believe the answer is:

nigeria

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

'the country' is the definition.
(Nigeria is an example)

'i regain' is the wordplay.
'i regain' can be anagrammed to 'NIGERIA'.
But, I'm not clear how this is indicated.

Can you help me to learn more?

(Other definitions for nigeria that I've seen before include "West African country, capital Lagos" , "Possible home for African" , "West African nation" , "Land in Africa" , "West African republic" .)

I've seen this clue in The Irish Independent.
