Broadcasting is another problem around Ireland (2,3,3)
I believe the answer is:
on the air
'broadcasting' is the definition.
(I've seen this before)
'another problem around ireland' is the wordplay.
I cannot really understand how this works, but
'another' could be 'e' (I've seen this in other clues) and 'e' is present in the answer.
'around' could be 'o' (I've seen this in other clues) and 'o' is found in the answer.
'ireland' could be 'ir' (I've seen this in other clues) and 'ir' is present in the answer.
This explanation may well be incorrect...
'is' is the link.
Can you help me to learn more?
(Other definitions for on the air that I've seen before include "Broadcasting (hence audible)" , "In the process of broadcasting, radio or TV" , "radio listeners can now hear?" , "Anti-hero engaged in live broadcast" .)
