Cloak for head (4)
I believe the answer is:
cape
This clue is a double definition.
'cloak' is the first definition.
(cape is a kind of cloak)
'head' is the second definition.
(both can mean a piece of land jutting over the sea)
'for' is the link.
(Other definitions for cape that I've seen before include "Head; garment" , "Short cloak" , "Short sleeveless garment" , "An old cloak or a headland" , "Loose cloak or promontory" .)
