Able to take girl into the country (6)
I believe the answer is:
canada
'the country' is the definition.
(Canada is an example)
'able to take girl' is the wordplay.
'able' becomes 'can'.
'to take' means one lot of letters go next to another.
'girl' becomes 'ada' (girl's name).
'can'+'ada'='CANADA'
'into' is the link.
(Other definitions for canada that I've seen before include "N.American nation" , "New World country" , "Ottawa is its capital" , "Country to north of USA" , "World's second-largest country by area" .)
