Island dweller heard from ship’s company? Very much (6)
I believe the answer is:
crusoe
'island dweller' is the definition.
(literary character Robinson Crusoe)
'heard from ship's company? very much' is the wordplay.
I cannot quite understand how this works, but
'very' could be 'so' (I've seen this in other clues) and 'so' is found in the answer.
This may be the basis of clue (or it may be nonsense).
(Other definitions for crusoe that I've seen before include "Daniel Defoe's hero" , "See 9" , "Novel shipwrecked sailor" , "Shipwreck victim" , "Abandoned" .)
