Picked note up in canteen before leaving (6)
I believe the answer is:
chosen
'up in canteen before leaving' is the definition.
I can't tell whether this defines the answer.
'picked note' is the wordplay.
'picked' becomes 'chose' (I've seen this before).
'note' becomes 'n' (abbreviation).
'chose'+'n'='CHOSEN'
Can you help me to learn more?
(Other definitions for chosen that I've seen before include "part of Asia once" , "If you're one of these few, you're very privileged" , "Elected, picked" , "'''Many are called, but few are ...'' (Bible) (6)'" , "Selected, preferred" .)
