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' suggests the final letters (the ending of the word).
'immortal' becomes 'odin' (Odin is an example).
The final 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" .)
