Island chap (3)
I believe the answer is:
man
I believe this is a double definition.
'island' is the first definition.
(Man is an example)
'chap' is the second definition.
(I've seen this before)
(Other definitions for man that I've seen before include "The most destructive and polluting animal" , "Where people compete to win TT" , "See 24" , "race" , "Board token; husband" .)
