Outlook for vocal piece that’s turned up on island (9)
I believe the answer is:
prognosis
'outlook' is the definition.
The definition and answer can be both acts as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'for vocal piece that's turned up on island' is the wordplay.
'for' becomes 'pro' (as in being 'pro' or in favour of something).
'vocal piece' becomes 'song' (I've seen this in another clue).
'that's turned up' says the letters should be written backwards (in a down clue, letters go up).
'on' says to put letters next to each other.
'island' becomes 'is' (abbreviation).
'song' in reverse letter order is 'gnos'.
'pro'+'gnos'+'is'='PROGNOSIS'
Can you help me to learn more?
(Other definitions for prognosis that I've seen before include "Forecast, outlook" , "Prediction as to how something will turn out" , "Medical prediction" , "Forecast of course of illness as by doctor" , "Medical opinion" .)
