'broadly-communicated' originates from the combination of 'broadly' and 'communicated', where 'broadly' means 'widely' and 'communicated' means 'shared or conveyed'.

'broadly' and 'communicated' have been used separately in English since the Middle Ages, but their combination into 'broadly-communicated' is a modern usage.

Initially, 'communicated' meant 'to share or convey information', and 'broadly' meant 'widely'. The combination retains these meanings, emphasizing the wide dissemination of information.
