Missed beginning of opera run that won an award (5)
I believe the answer is:
oscar
'award' is the definition.
(an Academy Award)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for oscar that I've seen before include "Phonetic code for O" , "- - Hammerstein (musicals)" , "- - Peterson, pianist" , "Cinema award" , "Develop again" .)
