Prominent feature of Anne's room (5,4)
I believe the answer is:
roman nose
'prominent feature' is the definition.
(I've seen this before)
'of anne's room' is the wordplay.
'of' is an anagram indicator (the answer comes from or 'of' the letters).
'annes'+'room'='annesroom'
'annesroom' anagrammed gives 'ROMAN NOSE'.
(Other definitions for roman nose that I've seen before include "feature with bridge" , "personal feature" , "prominent Italian feature" , "outstanding feature" .)
