Actress Ione (4)
I believe the answer is:
skye
'actress ione' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for skye that I've seen before include "Portree's isle" , "somewhere off Scotland's west coast" , "Large Scottish island" , "Scot. island, toll bridge" , "Island - keys (anag)" .)
