Judge female guitarist's figure? (7)
I believe the answer is:
sheriff
'judge' is the definition.
(I have seen 'Scottish judge ' mean 'sheriff' so perhaps 'judge' could also mean 'sheriff')
'female guitarist's figure?' is the wordplay.
'female' becomes 'she' ('she' refers to a woman).
'guitarist's figure?' becomes 'riff' (I can't explain this - if you can you should believe this answer much more).
'she'+'riff'='SHERIFF'
Can you help me to learn more?
(Other definitions for sheriff that I've seen before include "Crown's county officer" , "Local officer" , "Head of the posse" , "Lawman of the wild west" , "court officer" .)
