A man from a hot island (4)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
otis
'a man' is the definition.
'from a hot island' is the wordplay.
'from' indicates the answer is hidden within the clue.
'OTIS' is hidden within 'hot island'.
(Other definitions for otis that I've seen before include "US inventor" , "Miss -- Regrets, Cole Porter song" , "lift company" , "-- Redding, US singer" , "Place of worship; side part of head" .)
