Produce island broadcast (3)
I believe the answer is:
cos
This clue could be a double definition.
'produce' is the first definition.
(cos is a kind of produce)
'island broadcast' is the second definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.
Can you help me to learn more?
(Other definitions for cos that I've seen before include "holiday destination" , "Mozart fidelity-test opera" , "Islanders here" , "often associated with sin" , "Senior officers" .)
