'dancer' is the definition.
(Rudolf Nureyev)

I cannot understand how the rest of the clue works.

(Other definitions for nureyev that I've seen before include "Austrian ballet dancer, 1938-93" , "Russian-born ballet dancer, who partnered Fonteyn, d. 1993" , "Who might have danced" , "Famous Russian ballet dancer" , "Rudolf -------, (1938-93), dancer" .)

I've seen this clue in The Daily Express.
