Expert chart is technically inset (7)
I believe the answer is:
artiste
'expert' is the definition.
(I've seen this in another clue)
'chart is technically inset' is the wordplay.
'ARTISTE' is hidden within the letters.
But, I'm unsure how the hidden word is indicated.
Can you help me to learn more?
(Other definitions for artiste that I've seen before include "A sitter for a performer" , "Attires like entertainer" , "A sitter for creative person" , "Attires (anag.)" , "professional dancer?" .)
