Soprano stuck on Blue for mature folk (6)
I believe the answer is:
adults
'soprano stuck' is the definition.
I can't judge whether this defines the answer.
'blue for mature folk' is the wordplay.
'blue' becomes 'adult' (blue can mean pornographic or adult).
'for' is a charade indicator (letters next to each other).
'mature folk' becomes 's' (I can't explain this - if you can you should believe this answer much more).
'adult'+'s'='ADULTS'
'on' acts as a link.
Can you help me to learn more?
(Other definitions for adults that I've seen before include "Fully grown animals" , "Mature persons" , "Mature 25 down" , "Mature creatures" , "Fully developed and mature" .)
