The name of the artist? Once more, no one right! (6)
I believe the answer is:
renoir
'the name of the artist?' is the definition.
I can't tell whether this defines the answer.
'once more no one right' is the wordplay.
'once more' becomes 're' (prefix in words like 're-emerge' or 're-enter').
'one' becomes 'i' (Roman numeral).
'right' becomes 'r' (common abbreviation).
're'+'no'+'i'+'r'='RENOIR'
Can you help me to learn more?
(Other definitions for renoir that I've seen before include "Pierre-Auguste -, French Impressionist painter" , "Pierre ---, impressionist" , "Fr. impressionist ('La Loge')" , "French Impressionist painter, 1841-1919" , "French impressionist painter, d. 1919" .)
