Girl from America entertained by Poles (5)
I believe the answer is:
susan
'girl' is the definition.
'america entertained by poles' is the wordplay.
'america' becomes 'usa' (United States of America).
'entertained by' indicates putting letters inside (inserted letters are hosted or entertained).
'poles' becomes 'SN' (North and South poles).
'usa' placed within 'sn' is 'SUSAN'.
'from' is the link.
(Other definitions for susan that I've seen before include "sometimes lazy, passing round the condiments" , "Girl's name, meaning lily" , "Girl's name; lazy -" , "She's a black-eyed flower" , "female" .)
