Outlook for love: signs are mixed (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 you can see a link between them that I can't see?
'for love signs are mixed' is the wordplay.
'for' becomes 'pro' (as in being 'pro' something).
'love' becomes 'o' (love means zero in tennis).
'are mixed' indicates an anagram.
'o'+'signs'='osigns'
'osigns' anagrammed gives 'gnosis'.
'pro'+'gnosis'='PROGNOSIS'
Can you help me to learn more?
(Other definitions for prognosis that I've seen before include "Forecast of course of illness as by doctor" , "Forecast, outlook" , "Medical prediction" , "Medical opinion" , "Prediction as to how something will turn out" .)
