Work at home on island, on view (7)
I believe the answer is:
opinion
'view' is the definition.
('opinion' can be a synonym of 'view')
'work at home on island on' is the wordplay.
'work' becomes 'op' (abbreviation for opus**).
'at home' becomes 'in' ('in' can be similar in meaning to 'at home').
'on' is a charade indicator (letters next to each other).
'island' becomes 'i'.
'op'+'in'+'i'+'on'='OPINION'
(Other definitions for opinion that I've seen before include "Unproven belief" , "Point of view or thought on something" , "View held without positive proof" , "thinking" , "Assessment" .)
