Glen cultivated also in the country (7)
I believe the answer is:
england
'the country' is the definition.
(England is an example)
'glen cultivated also' is the wordplay.
'cultivated' is an anagram indicator.
'also' becomes 'and' (both can mean in addition).
'glen' with letters rearranged gives 'engl'.
'engl'+'and'='ENGLAND'
'in' acts as a link.
(Other definitions for england that I've seen before include "Lend nag to the neighbour" , "Albion" , "European country" , "Division of Great Britain" , "Lend nag out to the country" .)
