Etymology
The word 'rebroadcast' is a modern English compound formed in the 20th century. Its first element, the prefix 're-', is from Latin, signifying repetition. The second element, 'broadcast', is itself a compound from Old English 'brād' (wide, extensive) and Old Norse 'kasta' (to throw), originally an agricultural term for scattering seed. With the advent of radio, 'broadcast' was semantically extended to mean the wide dissemination of signals. Therefore, 'rebroadcast' logically follows this pattern, meaning literally "to cast widely again," capturing the act of retransmitting a program.
