Performer taking part when taking part is tedious (7)
I believe the answer is:
artiste
'performer' is the definition.
(an artiste is a performer or entertainer)
'part when taking part is tedious' is the wordplay.
'ARTISTE' is hidden within the letters.
However, I am uncertain how this is indicated.
'taking' acts as a link.
Can you help me to learn more?
(Other definitions for artiste that I've seen before include "A sitter for creative person" , "nightclub entertainer?" , "One entertaining" , "Player" , "A sitter for a performer" .)
