Poet, American, modelled nude (5)
I believe the answer is:
auden
'poet' is the definition.
(Auden is an example)
'american modelled nude' is the wordplay.
'american' becomes 'a' (common abbreviation - e.g. in organisation names).
'modelled' is an anagram indicator (I've seen this in other clues).
'nude' is an anagram of 'uden'.
'a'+'uden'='AUDEN'
(Other definitions for auden that I've seen before include "W. H. - , UK/US poet" , "W.H. --, English poet" , "Wystan Hugh -, poet" , "W. H. ... (British poet)" , "British-born American poet" .)
