Article written by US woman overseas (6)
I believe the answer is:
abroad
'overseas' is the definition.
(synonyms)
'article written by us woman' is the wordplay.
'article' becomes 'a' (indefinite article).
'written by' says to put letters next to each other.
'us woman' becomes 'broad'.
'a'+'broad'='ABROAD'
(Other definitions for abroad that I've seen before include "out of UK?" , "in Paris, perhaps" , "not in Britain" , "on the Continent" , "Pole would be so" .)
