Wanting a sort of clue Tramp gets to pick (8)
I believe the answer is:
plectrum
'to pick' is the definition.
(a guitar pick)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for plectrum that I've seen before include "Device for playing guitar" , "It's used to pluck, a guitar say" , "One for plucking guitar" , "Guitarist's implement" , "Implement for plucking guitar strings" .)
