No point in juveniles (3)
I believe the answer is:
nil
'no' is the definition.
(nil can mean zero or none)
'point in juveniles' is the wordplay.
'NIL' is hidden in amongst the letters.
But, I'm uncertain how the hidden word is indicated.
Can you help me to learn more?
(Other definitions for nil that I've seen before include "Zero, zilch" , "Nothing, zilch" , "Nothing - in Latin" , "Score of nought" , "Non-existent" .)
