TV programme that broadcasts idea in town (10)
I believe the answer is:
nationwide
'tv programme' is the definition.
The definition and answer are not the same part of speech.
'broadcasts idea in town' is the wordplay.
'broadcasts' indicates an anagram (I've seen 'broadcast' mean this (letters scattered or cast around)).
'idea'+'in'+'town'='ideaintown'
'ideaintown' anagrammed gives 'NATIONWIDE'.
'that' is the link.
Can you help me to learn more?
(Other definitions for nationwide that I've seen before include "Across the whole country" , "for all of us" .)
