Poles taking in country girl (5)
I believe the answer is:
susan
'girl' is the definition.
'poles taking in country' is the wordplay.
'poles' becomes 'SN' (North and South poles).
'taking in' is an insertion indicator.
'country' becomes 'usa' (USA is an example).
'sn' enclosing 'usa' is 'SUSAN'.
(Other definitions for susan that I've seen before include "When lazy, she's a revolving tray on a dining table" , "with blooming black eye?" , "Girl's name, meaning lily" , "Black-eyed -; lazy -" , "Girl's name; lazy -" .)
