She makes pink noise (5)
I believe the answer is:
rosie
This clue might be a double definition.
'she' is the first definition.
'pink noise' is the second definition.
The definition suggests a singular noun which matches the answer.
'makes' acts as a link.
Can you help me to learn more?
(Other definitions for rosie that I've seen before include "Char" , "riveting woman in 40s?" , "Old song: 'Sweet ..... O'Grady'" , "Cider with - (Laurie Lee)" , "Girl's name" .)
