Sculptor, never ending, immortal (5)
I believe the answer is:
rodin
'sculptor' is the definition.
(Auguste Rodin was a French sculptor)
'never ending immortal' is the wordplay.
'ending' says to take the final letters.
'immortal' becomes 'odin' (Odin is an example).
The last letter of 'never' is 'r'.
'r'+'odin'='RODIN'
(Other definitions for rodin that I've seen before include "Kiss I'm famous for" , "French sculptor of The Kiss, d. 1917" , "French manual worker" , "French artist manually" , "Famous French figure" .)
