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' indicates one should take the final letters (the ending of the word).
'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" .)
