I rue Oprah broadcast, ignoring queen's happiness (8)

I believe the answer is:

euphoria

I'm a little stuck... Click here to teach me more about this clue!

'happiness' is the definition.
(I know that happiness can be written as euphoria)

I don't understand how the remainder of the clue works.

Can you help me to learn more?

(Other definitions for euphoria that I've seen before include "Great happiness and exhilaration" , "feeling good?" , "Rapture" , "Sense of wellbeing" , "Intense happy feeling" .)

I've seen this clue in The Telegraph.
