The assurance of a true artist (3)
I believe the answer is:
tis
'the assurance of a true artist' is the definition.
I can't judge whether this defines the answer.
'of a true artist' is the wordplay.
'of' indicates a hidden word.
'TIS' can be found hidden inside 'true artist'.
Can you help me to learn more?
(Other definitions for tis that I've seen before include "... the season to be jolly" , "Pacific trees" , "For poet, that's" , "Contraction of it is" , "McCourt work" .)
