In opera maybe such events can't be covered (4-3)
I believe the answer is:
open-air
'events can't be covered' is the definition.
I can't tell whether this defines the answer.
'in opera maybe' is the wordplay.
'maybe' indicates an anagram.
'in'+'opera'='inopera'
'inopera' anagrammed gives 'OPEN-AIR'.
'such' acts as a link.
Can you help me to learn more?
(Other definitions for open-air that I've seen before include "Taking place outdoors" , "not below roof" , "Exposed to the elements" , "Outdoor" , "outside" .)
