American article on where Queen Victoria died (5)
I believe the answer is:
iowan
'american' is the definition.
(someone from Iowa)
'article on where queen victoria died' is the wordplay.
'article' becomes 'an' (indefinite article).
'on' means one lot of letters go next to another.
'where queen victoria died' becomes 'IOW' (Isle of Wight).
'an' put after 'iow' is 'IOWAN'.
(Other definitions for iowan that I've seen before include "Someone from the Midwest - a wino? (anag)" , "Statesman" , "US resident" , "From one US state" , "From Des Moines, say?" .)
