In life, wonderful blessings are not common (3)
I believe the answer is:
few
'not common' is the definition.
Both the definition and answer are adjectives. Perhaps you can see a link between them that I can't see?
'in life wonderful blessings' is the wordplay.
'in' indicates a hidden word.
'FEW' is hidden within 'life wonderful blessings'.
'are' acts as a link.
Can you help me to learn more?
(Other definitions for few that I've seen before include "Only one or two" , "Considerable number, ironically" , "Hardly anyone" , "Indefinite but small number" , "Indefinite small amount" .)
