Unforeseen difficulty of Italian female wearing shroud (7)
I believe the answer is:
pitfall
'unforeseen difficulty' is the definition.
(I've seen this before)
'italian female wearing shroud' is the wordplay.
'italian' becomes 'it'.
'female' becomes 'f' (abbreviation).
'wearing' means one lot of letters goes inside another.
'shroud' becomes 'pall' ('pall' can be a synonym of 'shroud').
'it'+'f'='itf'
'itf' inserted into 'pall' is 'PITFALL'.
'of' acts as a link.
(Other definitions for pitfall that I've seen before include "Hazard" , "Unexpected difficulty or danger" , "Trap in the form of a concealed hole" , "Unexpected problem" , "Unsuspected danger or difficulty - for miner?" .)
