Others take forcible control of broadcast (4)
I believe the answer is:
rest
'others' is the definition.
(eg the rest of a group)
'take forcible control of broadcast' is the wordplay.
I cannot really understand how this works, but
'take' could be 'r' (abbreviation for 'recipe', Latin for 'take') and 'r' is found in the answer.
The remaining letters 'est' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for rest that I've seen before include "Repose - remainder" , "Holiday" , "Inactivity" , "Change is as good as this, they say" , "lean" .)
