Our GP treated musicians (5)
I believe the answer is:
group
'our gp treated musicians' is the definition.
I can't judge whether this defines the answer.
'our gp treated' is the wordplay.
'treated' indicates an anagram.
'our'+'gp'='ourgp'
'ourgp' with letters rearranged gives 'GROUP'.
Can you help me to learn more?
(Other definitions for group that I've seen before include "Set, faction" , "Band; cluster" , "Set (of people)" , "Take That, perhaps" , "Collective unit" .)
