US city, one beginning to recognise artist (6)
I believe the answer is:
renoir
'artist' is the definition.
(French artist Pierre-Auguste Renoir)
'us city one beginning to recognise' is the wordplay.
'us city' becomes 'Reno' (city in Nevada).
'one' becomes 'i' (Roman numeral).
'beginning to' suggests taking the first letters.
The initial letter of 'recognise' is 'r'.
'reno'+'i'+'r'='RENOIR'
(Other definitions for renoir that I've seen before include "French artist" , "No, I err about the great painter" , "Pierre ---, impressionist" , "French impressionist painter, d. 1919" , "Jean -, Fr. film director, son of painter" .)
