Princess featuring in American newspapers (4)
I believe the answer is:
anne
'princess' is the definition.
(Princess Anne, daughter of Queen Elizabeth)
'in american newspapers' is the wordplay.
'in' indicates the answer is hidden within the clue.
'ANNE' is hidden within 'american newspapers'.
'featuring' acts as a link.
(Other definitions for anne that I've seen before include "Female name" , "- - of Cleves" , "Green Gables girl" , "Queen's name" , "British queen" .)
