Clumsy when famous W.G. had gone! (9)
I believe the answer is:
graceless
'clumsy' is the definition.
(I've seen this before)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for graceless that I've seen before include "Lacking elegance" , "Awkward" , "Indecorous" , "clumsy" .)
