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 in amongst the letters.
But, I'm not sure how the hidden word 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" .)
