Naked bloke chasing Black Beauty (5)
I believe the answer is:
belle
'beauty' is the definition.
(I've seen this in another clue)
'naked bloke chasing black' is the wordplay.
'naked' says to take the centre (outside letters removed so centre is unclothed).
'bloke' becomes 'yobbo' (I have seen 'Tough bloke' mean 'yobbo' so perhaps 'bloke' could also mean 'yobbo').
'chasing black' becomes 'elle' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
The middle letter of 'yobbo' is 'b'.
'b'+'elle'='BELLE'
Can you help me to learn more?
(Other definitions for belle that I've seen before include "Most attractive girl" , "Beautiful girl" , "Attractive woman" , "Beautiful woman - of the ball?" , "-- Epoque, before the Great War" .)
