A gentle shake showing refinement (7)
I believe the answer is:
elegant
'a gentle shake showing refinement' is the definition.
I can't judge whether this definition defines the answer.
'a gentle shake' is the wordplay.
'shake' indicates anagramming the letters.
'a'+'gentle'='agentle'
'agentle' anagrammed gives 'ELEGANT'.
Can you help me to learn more?
(Other definitions for elegant that I've seen before include "Well-dressed" , "Gracefully stylish" , "Handsome" , "Fine" , "Stylish in appearance, a gentle kind" .)
