Capri, perhaps, covered in hotels Italians erected (4)
I believe the answer is:
isle
'capri' is the definition.
(I've seen this in another clue)
'covered in hotels italians erected' is the wordplay.
'covered in' indicates the answer is hidden within the clue.
'erected' says the letters should be written backwards (in a down clue, letters go up).
'elsi' is hidden within 'hotels italians'.
'elsi' written backwards gives 'ISLE'.
'perhaps' is the link.
(Other definitions for isle that I've seen before include "Detached territory" , "Spot (in ocean)" , "See 11 Across" , "-- of Ely, Dogs, Man" , "Fair ---, knitting style" .)
