Bit of American broadcast overheard (4)
I believe the answer is:
cent
'bit of american' is the definition.
'cent' can be an answer for 'bit' (thesaurus). I am unsure of the 'of american' bit.
'broadcast overheard' is the wordplay.
'broadcast' becomes 'sent' (sent or transmitted as a broadcast).
'overheard' shows a homophone (sound like).
'sent' is a homophone of 'CENT'.
Can you help me to learn more?
(Other definitions for cent that I've seen before include "Small monetary unit" , "Tiny coin" , "change from Colorado!" , "Little bit of money" , "One-hundreth part of a currency" .)
