Play pluckily (5)
I believe the answer is:
twang
'play pluckily' is the definition.
The definition and answer can be both human attributes as well as being singular nouns.
Perhaps there's an association between them I don't understand?
This is the entire clue.
Can you help me to learn more?
(Other definitions for twang that I've seen before include "Sharp vibrating sound" , "way of speaking" , "Nasal or musical sound" , "Sound of a tense wire or bowstring being plucked" , "The Sound of Music?" .)
