Blare noisily at Tony (5)
I believe the answer is:
blair
'tony' is the definition.
(I've seen this before)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for blair that I've seen before include "A political leader" , "Is the politician a Libra?" , "Writer" , "George Orwell's real name" , "Tony ..., modern P.M." .)
