Enjoy ballet regularly, being blue-blooded (5)
I believe the answer is:
noble
'blue-blooded' is the definition.
(similar in meaning)
'enjoy ballet regularly' is the wordplay.
'regularly' indicates alternate letters (regularly take one letter, leave next etc.).
'enjoy'+'ballet'='enjoyballet'
The alternate letters of 'enjoyballet' are 'NOBLE'.
'being' acts as a link.
(Other definitions for noble that I've seen before include "like Basie or Ellington?" , "Of high rank or birth" , "old British coin" , "Grand, magnanimous" , "Worthy" .)
